Plastic Compression Tube Fittings for Water
- Temperature Range: -40° to 200° F
- Tubing: Use with hard (Durometer 55D-Rockwell R110) nylon plastic or polypropylene plastic
Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments. Fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly. The sleeve compresses the tubing as you tighten the nut, creating a strong seal. Fittings are also known as flareless fittings.
Tube supports (sold separately) are recommended if you want to use the fittings with soft nylon and polypropylene tubing to prevent the tube from collapsing.

Nuts with Built-In Sleeve for Plastic Compression Tube Fittings for Water
- Temperature Range: -40° to 200° F
- Tubing: Use with hard (Durometer 55D-Rockwell R110) nylon plastic or polypropylene plastic
Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. Nuts are moisture-resistant acetal, so they won't absorb water and soften, even in high-humidity environments.

Sleeves for Tight-Seal Brass Compression Tube Fittings for Air and Water
- Tubing: Use with firm (Durometer 95A) EVA plastic or polyurethane rubber
- Specifications Met: SAE J512
- Temperature Range: -65° to 250° F
Use these sleeves with tight-seal brass compression nuts and fittings to create a seal on plastic and rubber tubing. They are acetal, so they won’t damage tubing.

Plastic Quick-Disconnect Tube Couplings for Air and Water
Lighter in weight than their metal counterparts, these quick-disconnect couplings are plastic. They consist of a plug and a socket that allow you to frequently connect and disconnect your line.
Latch-lock sockets disconnect by pressing the latch.
Acetal plugs and sockets are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments. Plug and Sockets with shut-off have a valve to stop the flow when the coupling is separated, so air or water won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.

Compression plugs and sockets have a sleeve (ferrule) that compresses the tubing and forms a seal when you tighten the nut.
Through-wall plugs and sockets are also known as bulkhead and panel-mount plugs and sockets; they mount through your wall or panel to create an inlet or outlet.

Quick-Disconnect Tube Couplings for Food and Beverage
- Temperature Range:
Acetal Plastic: -40° to 180° F
Polypropylene Plastic: 32° to 160° F - Tubing:

Couplings consist of a plug and a socket (sold separately) that join with a latch, so you can frequently connect and disconnect your line. To connect, insert the plug into the socket; to disconnect, press the latch on the socket and remove the plug. They’re made of FDA-approved materials, including moisture-resistant plastic that won’t absorb liquid and lose strength, even in high-humidity food and beverage applications.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated, so fluid won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.

Compression plugs have a sleeve (ferrule) that compresses the tubing and forms a seal when you tighten the nut.
