Brass push-fit adapter for 5/32 in tube

This brass adapter provides a straight push-to-connect fitting for 5/32 in outer-diameter tube on one side and a #10-32 UNF thread on the other. It is rated for 290 psi maximum operating pressure and 175 degrees F maximum operating temperature. The fitting is 17/32 in overall length and includes no pre-applied thread sealant.

Vacuum-line installers and pneumatic builders

Suits technicians assembling vacuum or low-pressure pneumatic circuits who need a compact straight adapter between push-fit tube and a #10-32 port. Not suited for systems exceeding the stated pressure or temperature limits, for applications requiring a different thread size, or for installations that demand a pre-sealed thread.

#10-32 UNF thread and 5/32 in push-to-connect

The single specification that determines fit is the combination of a #10-32 UNF male thread on side B and a 5/32 in push-to-connect port on side A. Verify both the thread and the tube diameter against your port and tubing before ordering.

Questions about this item

Does the brass adapter run hot or draw power when it stays under vacuum all day?

The brass fitting is a passive component with no electrical draw and generates no heat during continuous vacuum service.

What tube and thread must already be on the machine for this 5/32 in push-fit adapter to seal?

The machine needs a 5/32 in or 4 mm outer-diameter tube for the push-to-connect side and a #10-32 UNF female port for the threaded side.

Will the 290 psi brass adapter hold up on a legacy system that still uses older 5/32 in nylon tubing?

Yes, the straight adapter accepts standard 5/32 in tubing and its 290 psi rating matches or exceeds typical legacy vacuum line pressures.
