12 mm Push-Fit Adapter

The SMC KQ2H12-02AS is a brass push-fit adapter designed for pneumatic and non-potable water systems. It connects 12 mm outer diameter tubing to a 1/4 inch male BSPT thread. The fitting includes pre-applied thread sealant for faster installation without additional sealing compounds.

Sustained Pressure and Temperature Limits

The adapter maintains integrity up to a maximum operating pressure of 145 psi and a maximum operating temperature of 140 Degrees F. Brass construction provides consistent dimensional stability under continuous pressurised service. Performance remains reliable within these published limits for air and non-potable water media.

BSPT Thread and Push-to-Connect Constraints

The male BSPT thread requires a matching female BSPT port; it is not compatible with NPT or other thread standards without an adapter. The push-to-connect side accepts only 12 mm OD tubing within specified tolerances. The fixed 1/4 inch thread size and 28 11/16 mm overall length define the installation envelope.

Questions about this item

How much heat can the brass body of the KQ2H12-02AS handle during continuous use?

The fitting is rated for a maximum operating temperature of 140 Degrees F, so the brass body will handle that heat level all day.

What tube and thread sizes must my existing system have to connect this 12 mm push-fit adapter?

Your system needs a 12 mm outer-diameter tube for the push-to-connect side and a 1/4 in male BSPT threaded port for the other side.

Will the 1/4 in BSPT thread on this adapter seal properly against the older tapered ports on my current manifold?

Yes, the 1/4 in male BSPT thread matches standard tapered ports, and the fitting comes with pre-applied thread sealant for a reliable seal.
