Midland Industries 20644C Push-to-connect Cap 5/16 Inch

Product Description

The MIDLAND INDUSTRIES 20644C is a composite-body push-to-connect cap designed to terminate open tubing ends in pneumatic and fluid distribution systems. The cap installs without tools by pressing directly onto compatible tubing, creating a secure seal that blocks flow and prevents contamination. At 0.005 pounds, this lightweight fitting is suited for applications where minimizing system weight matters. Licensed plumbers, HVAC technicians, and fluid system installers use this type of cap during service, testing, and staged installation work when a line must be temporarily or permanently capped off.

This push-to-connect cap is used in residential and light commercial plumbing, HVAC, and pneumatic tubing systems. It fits 5/16 inch outside-diameter tubing and is appropriate wherever a clean, tool-free termination is needed. Common scenarios include capping unused branch ports, isolating sections of tubing during phased installations, and protecting open line ends during transport or storage. The composite body construction makes it a practical choice for applications where a full brass fitting is not required.

Installation Notes

Depressurize and isolate the tubing line before installing or removing any push-to-connect fitting. Verify tubing outside diameter and ensure the cut end is clean, square, and free of burrs before pressing the cap onto the tube. This fitting is intended for installation by licensed plumbers or HVAC technicians working in accordance with applicable local codes. Do not exceed the pressure or temperature ratings specified for the tubing system in use.
