Seal-Lok
 The Seal-Lok
fitting is an O-ring face seal type fitting that consists of a nut, a fitting
body, an O-ring and a sleeve.
A flat face sleeve is flanged or brazed to the tube and when the fitting is
assembled, it compresses an O-ring in a precision machined groove in the fitting
body to form a leak tight seal. Seal-Lok fittings are suitable for any range of
tube wall thick-ness and are also readily adaptable to pipe, metric tubing and
hose. The Seal-Lok connection can be made with either metric or inch tubing by
choosing the appropriate sleeve. There are over thirty different body shapes and straights to choose from for
specific applications. The body face has a groove which contains a high
durometer O-ring that is held captive during installation. In addition, the
Seal-Lok fitting body shapes are forged for added strength and longer service
life. Straight products are made from cold drawn barstock. Seal-Lok fittings are manufactured with a captive O-ring groove
(CORG) design for prevention of O-ring fall-out prior to final assembly.
Triple-Lok
 The Triple-Lok tube
fitting consists of three pieces: the body, the nut and the sleeve. The tube end
is flared at a mating 37° angle and sandwiched between the fitting nose (seat)
and the sleeve creating an effective seal between the fitting nose and tube
flare or hose. Parker’s Triple-Lok fittings are
manufactured in steel, 316 stainless steel and brass for optimum fluid
compatibility and corrosion resistance. Furthermore, available sizes range from
1/8" tube O.D. to 2" tube O.D. in several configurations. (Standard ports include:
SAE, straight thread ISO-6149, NPT, BSPT, BSPP and DIN.) The Triple-Lok tube fitting is also
readily available for metric tubing and hose adapter applications. Simply by
changing the industry standard sleeve, the same Triple-Lok body can be adapted
to metric tubing in sizes ranging from 6 mm tube O.D. to 38 mm tube O.D.
Likewise, by using only the body without the nut and sleeve, the Triple-Lok
fitting is used as an industry standard hose adapter.
Ferulok Fittings
The Ferulok fitting design and performance
capabilities far exceed the strict requirements of SAE and military standards.
The Ferulok fitting is a flareless fitting that consists of a body, a one-piece
precision machined ferrule, and a nut. On assembly, the ferrule
"bites" into the outer surface of the tube with sufficient strength to
hold the tube against pressure, without significant distortion of the inside
tube diameter. The ferrule also forms a pressure seal against the fitting body.
Ferulok fittings allow the fitting assembler to visually inspect the bite
quality, thus significantly minimizing the risk of improper assembly and related
service problems. Ferulok fittings are especially suitable for use with tube
wall thicknesses ranging from medium to extra heavy.
Intru-Lok
 The Intru-Lok fitting is a flareless fitting that
consists of a body, a one-piece precision machined ferrule, and a nut. On
assembly, the ferrule "bites" into the outer surface of the tube with
sufficient strength to hold the tube against pressure. The ferrule also forms a
pressure seal against the fitting body. Intru-Lok fittings allow the fitting
assembler to visually inspect the bite quality, thus significantly minimizing
the risk of improper assembly and related service problems. Intru-Lok fittings
are routinely used in markets, such as: Machine tools, chemical, oil refineries,
paper making, thermoplastics processing, air and lube lines, pilot lines, panel
boards, etc.
Pipe Fittings and Adapters
There are many types of threads
used throughout the world. This Section contains adapters with just a
few of those many thread types including NPT, NPTF, NPSM, BSPT, BSPP,
SAE UN/UNF, and Metric. All the threads in this section conform to
industry specifications.
 JIS
Japanese Industrial Standard (JIS) fittings were
introduced by Parker in North America in the early 1990s to address market
requirements for OEM and replacement JIS fittings. The JIS fittings are designed
with 30° male flare and 30° female seats and each incorporate BSP (British
Standard Pipe) threads. These fittings are typically utilized as hose adapters
on equipment designed and/or manufactured in Japan and Korea.
EO Fittings
EO fittings are the most widely used bite
type fittings in the world. The EO fitting is a flareless metric fitting that
consists of a body, progressive ring (ferrule) and nut. On assembly, two cutting
edges of the ferrule "bite" into the outer surface of the tube
ensuring the necessary holding power for high operating pressures. Available in
three series, the EO tube fittings and accessories are manufactured in
accordance with DIN 2353 for fluid applications. Three series of EO tube
fittings (LL, L and S) and accessories are manufactured in accordance with DIN
2353 on the basis of decades of experience. The three components of EO fittings
are designed and manufactured to produce a strong, reliable, leak-free joint
upon proper assembly.
EO-2
Fittings
The heart of the EO-2 fitting is the new
EO-2 functional nut with which previously metalically sealed tube connections
can now be soft sealed. Naturally, all fittings in the EO-2 series are fully
compatible with our Ermeto Original range of products and can be combined with
these. For more demanding applications, in particular for new designs, we
recommend the use of EO-2 fittings. EO-2, the latest development from Parker-Ermeto,
is a fitting system with a soft seal on the tube side and a 24° cone according
to ISO 8434-1/DIN 2353. The soft sealing and retaining rings are combined in a
pair and are inserted into the internal thread of the nut in such a manner that
they cannot fall out, so that these three parts from one functional element.
This functional nut simplifies handling of the fitting and helps to minimize
storage and procurement costs.
 Tube, Pipe and Hose Clamps
Parker offers a full line of
clamps for inch and metric tube (1/4" through 2" and 6mm
through 50mm), inch pipe (1/2" through 1-1/2") and 100R1 hose
sizes 1/4" through 1-1/2". Proper clamping of tube, pipe and
hose can eliminate problems caused by shocks and vibration in most
hydraulic systems.
Tube Cutters
Parker-Tube Fittings Division hand tube cutters are designed
to make uniform clean square cuts easier and with the least possible
burrs. Hand Tube Cutters use a built-in deburring blade on each cutter
for removal of any I.D. burrs.
Saws
Parker's Tru-Kut® saw vise is designed for
providing an accurate guide for cutting tube square within ±1° with a
hacksaw. For higher production, Parker also offers the power 910461
power cut-off saw, which is designed to operate at low speed to prevent
work hardening the tube end. The saw will cut 1/4" through 2"
copper, brass, aluminum, steel and stainless steel tube. An adequate
supply of cutting fluid is provided by an internal recalculating pump.
The unit is designed for bench mounting and operates on 110v power
supply.
Deburr Tools
A quick twist of the wrist will deburr either the O.D. or the
I.D. of the tube end. Parker’s In-Ex® deburring tools
can be used on annealed steel, stainless steel, copper and aluminum, for
tube sizes 1/8" to 1 5/8" O.D. Parker also offers
the 972125 Power Deburr Machine for medium production applications. This
machine operates on a 110V power supply and is for use on annealed
steel, stainless steel, copper and aluminum. For tube sizes 1/4"
through 2" O.D.
Wrenches
Easy access ratchet wrench speeds fitting installation in
tight locations. Rugged, snap-action jaws can be opened over tube lines,
locked onto fitting hex and ratcheted within 1/8 turn. Full six point
contact prevents fitting distortion common with wrench slippage. Ideal
for tube line installations where compact runs require a multiple
fitting make-up, disassembly and remakes. 360°s snap-action ratchet
wrench for hex sizes from 3/8" to 2 1/4" across the flats and
metric from 10mm to 22mm. Inch sizes meet government
specifications and are listed as NSN-5120-00-474-7227.
Tube Benders
Parker hand benders include built-in features to help you make
accurate bends without kinks or wrinkles and with minimum flattening in
tubing, from size 2 (1/8" O.D.) to 16 (1" O.D.). Parker’s
larger benders include manual and hydraulic models, to meet any
operating need for production or maintenance in the shop or in the
field. Accessories are available to handle bends in a variety of tubing
material from size 4 (1/4" O.D.) to size 32 (2" O.D.).
Flanging Equipment
The Parflange® machines have been designed to
flange and flare tubing, specifically for use with Parker Seal-Lok
(O-ring face seal) and Triple-Lok (37° flare) fittings. See Bulletin
4390-1040 or 4390-1025 for more details.
Brazing Equipment
Parker Seal-Lok fittings can be easily brazed by using
Parker’s Multi-Flame Torches.
Tube Flaring Tools
Parker makes the right type and size of flaring tool to meet
the requirements of your job, from pocket-size hand flaring tools to
electric and hydraulically powered models. Each one is designed to help
you produce correct concentric flares, of the correct flare diameter,
for dependable joints that are free from pull out under high pressures.
Pre-setting Tools
Parker Ferulok, EO and EO-2 fittings can be assembled more
readily by using either the Ferulset® or VOMO hand
pre-setter, the hydraulic powered Hyferset and Hydra-Tool or the
electric powered EOMAT III®. All five assembly tools
ensure strong, reliable ferrule pre-sets on the tubing.
Tube Preparation Centers
Parker offers two types of Tube Preparation Centers: the TP432
and the TP1025. Both are designed for preparation required of tube ends
to be completed in one location. The TP432 performs four separate
operations: cutting, deburring, flaring for Triple-Lok fittings and
ferrule pre-setting for Ferulok, EO and EO-2 fittings. Four operations
can also be performed by the TP1025: cutting, deburring, flanging for
Seal-Lok fittings and flaring for Triple-Lok fittings.
