TrueSeal™ Thermoplastic Push-In Fittings
The patented* TrueSeal™ push-to-connect thermoplastic fttings are
light weight, Field Attachable, and connect to plastic tubing without
the use of tools.
Features
• All components in TrueSeal™ fttings are manufactured from FDA
compliant materials and are NSF-51 listed for contact with food.
• Gray acetal TrueSeal™ fttings meet NSF-61 requirements for
drinking water (potable water) system components.
• All-plastic body designs offer reduced weight, eliminate rust,
corrosion, and system contamination in applications where metal
components cannot be tolerated.
• Collets are offered in either a patented all-plastic design for use
with fexible tubing or with a metal grip edge made from 300 series
stainless steel for use on all tubing including copper.
• Extra deep tube seat in ftting body provides support to
reduce side-load leakage.
• Elastomer o-ring seal provides positive compression on
tubing O.D. in vacuum or pressure applications.
• Removable collet design permits o-ring replacement in the feld.
Collets are available in colors for easy color coding of systems.
• Tube stem adapters provide a wide range of tube-to-port
jump size potential and allow elbows and tees to swivel for positive
tube routing alignment. Connections made with metal gripper col-
lets, may require tube stems to be replaced upon reconnection.
Applications
TrueSeal™ fttings fnd wide acceptance in water conditioning, fltra-
tion, and reverse osmosis industries and on water, soft drink, beer,
wine, and condiment dispensing equipment. Industrial applications
range from vacuum to low-pressure hydraulic and pneumatic systems
on robotics, air logic, packaging/flling equipment, and conveyors. Ink
and dye transfer, lubrication and cooling lines on presses, machine
tools, ion implanting devices—all rely on TrueSeal™.
Standard Materials
Working Pressure
TrueSeal™ fttings are rated for the pressures listed below or at 1/4
(one-fourth) of the rated burst pressure of the tubing being used
(whichever is less).
Note: Provide adequate fail-safe mechanisms such as leakage detection sensors, automatic
shut-off controls or other industry and code appropriate fail-safe devices in the design of your
water-handling appliance to protect against personal injury and property damage. Plastic ft-
tings containing an o-ring have a fnite life depending on the environment, media and severity
of the application. Frequent inspections and replacement of the ftting when anomalies are
found is recommended.

Series NR tubing at 73°F.
• Actual working pressures will be lower at elevated temperatures.

• Meets pressure integrity tests of NSF-53 and NSF-58
Tubing
Parker TrueSeal™ fttings with all plastic collets can be used with the
following tubing materials: polyethylene, polypropylene, nylon, vinyl,
fuoropolymer, and polyurethane (3/8" and 1/2" polyurethane and all
sizes of vinyl should use tube supports). TrueSeal™ fttings with metal
gripper collets can be used with tubing listed above and soft copper
tubing. For stainless steel or glass tubing or all other metal tubing,
consult factory.

Assembly Instructions
1. Cut tubing square and clean. (Use a Parker plastic tube cutter, Part
No. PTC.)
2. Mark from end of tube the length of insertion (see table above).
3. Push tube into the ftting until it bottoms out.
4. To remove, depress collet and pull tubing out.
5. Use TrueSealant™ (Part No. PTS) on threads.
