Push-Fit Adapter for 5/16 Tube and 1/4 Pipe
This pack of ten nickel-plated brass connectors joins 5/16 inch tube to a 1/4 inch male BSPT thread using a push-to-connect design. The C36000 brass body includes pre-applied thread sealant for a secure seal. It suits pneumatic or vacuum lines in automotive and workshop plumbing.
Check tube diameter and thread type before ordering
Verify that your tubing has a 5/16 inch outer diameter and that the mating port uses a 1/4 inch male BSPT thread. The fitting relies on a push-to-connect seal rather than a compression nut, so the tube must be clean and cut squarely. Ensure the system pressure and temperature stay within the rated limits.
Rated for 290 psi and 175 Degrees F under
The connector maintains its seal at the maximum operating pressure of 290 psi and the maximum operating temperature of 175 Degrees F during continuous use. Nickel plating on the C36000 brass resists corrosion over long service periods. The pre-applied thread sealant remains effective without re-tightening.

Questions about this item
Does the pack of ten male connectors include any tubing or thread-seal tape, or must those be purchased separately?
The pack contains only the ten nickel-plated brass push-fit connectors with pre-applied thread sealant; 5/16 inch tubing and any additional sealing tape are not included and must be sourced separately.
How do I confirm that the 5/16 inch tube and 1/4 inch BSPT thread sizes match my existing pneumatic line?
Measure the tube outside diameter — it must be exactly 5/16 inch — and verify the mating port uses a 1/4 inch male BSPT thread; the connector’s push-to-connect end accepts the tube while the threaded end screws into the port.
Will the 290 psi pressure rating hold up on a shop compressor that cycles to 175 °F?
Yes — the brass body is rated for 290 psi maximum operating pressure and 175 °F maximum operating temperature, covering typical shop-air conditions.
