Midland Industries 20631 Push-to-connect Male Connector

Product Description

The MIDLAND INDUSTRIES 20631 is a composite-body push-to-connect male connector designed to join 4 mm OD tubing to a 1/4-inch male BSPT threaded port. The fitting uses a push-to-connect mechanism on one end for fast, tool-free tube insertion and a 1/4-19 BSPT male thread on the other for secure engagement with corresponding female BSPT ports. The composite body is nickel-plated for corrosion resistance. Rated to 150 psi and suitable for use across a temperature range of 32 to 140 degrees F, this connector suits pneumatic and fluid-control applications in light industrial and trade settings.

This fitting is used in pneumatic control systems, instrumentation lines, and compressed-air circuits where metric tubing must transition to a BSPT-threaded port. The 4 mm push-to-connect side accepts standard metric tubing without additional tools or ferrules. The male BSPT thread follows the 1/4-19 standard, making it appropriate for equipment with British Standard Pipe Taper ports. Plumbers, pipefitters, and industrial maintenance technicians working on compressed-air or pneumatic control panels are the typical installers.

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic and fluid-control systems using 4 mm OD metric tubing and 1/4-19 male BSPT threaded ports.

Installation Notes

Shut off and depressurize the system completely before removing or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect end. Apply thread sealant appropriate for BSPT connections on the male thread side and verify engagement depth before repressurizing. Installation should comply with applicable local and national plumbing or pneumatic system codes.
