This 1/8 male universal thread is designed to connect to matching-size flat-faced female NPT, BSPT and BSPP threaded ports. It is a specifically engineered Vacuforce fitting, not a claim that ordinary thread forms are interchangeable.

It is designed for matching-size flat-faced female NPT, BSPT and BSPP ports. The female port must provide the required flat-faced sealing surface; check the installation condition.

This fitting is listed for the 50mm cup family; use the compatible cup-family list above and verify the cup mounting bore and assembly dimensions.

One male universal design supports common matching-size female port standards, simplifying machine builds, spares and maintenance across equipment using mixed NPT/BSP ports.

Thread compatibility determines mounting. The actual holding force depends on the suction cup sealing area, vacuum level, leakage and part motion; check adequate flow through the assembly.

This compatibility claim applies to flat-faced female ports. Do not assume the specified seal will work on an unsuitable port face or damaged sealing surface.
