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.
Fittings with acrylic thread sealant offer extra protection against leaks.
NPTF (Dryseal) threads are compatible with NPT threads.

Quick-Assembly Brass Compression Tube Fittings for Air and Water
- Temperature Range: 0° to 150° F
- Tubing: Fittings with acetal plastic sleeves: Use with (firm or hard) polyethylene plastic or polypropylene plastic
Fittings with brass sleeves: Use with (firm or hard) nylon plastic, polyethylene plastic or polypropylene plastic
These 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. They are brass for good corrosion resistance.
Tube supports are recommended if you want to use the fittings with soft polypropylene and polyethylene tubing to prevent the tube from collapsing.
NPTF (Dryseal) threads are compatible with NPT threads.
