Moisture-Resistant Push-to-Connect
Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water,
except Manifolds with Swivel: Air, Water - Temperature Range: 32° to 100° F
- Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber
These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. They have good corrosion resistance.
Nickel-plated brass fittings have better corrosion resistance than unfinished brass fittings.
Fittings with thread sealant offer extra protection against leaks.

Manifold Adapters (Intermittent Swivel), Male Threaded Pipe × Tube
Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.

Brass Push-to-Connect Tube Fittings for Air
- Temperature Range: 0° to 200° F, except nylon plastic fittings are 0° to 150° F
- Tubing: Use with hard nylon plastic or polyethylene plastic
These fittings offer good protection against corrosive environments. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting.
NPTF (Dryseal) threads are compatible with NPT threads.
