Parker 20-4-5/32 Barbed Tube Plug Brass 5/32 Inch

Product Description

The PARKER 20-4-5/32 is a multi-barb tube plug designed to seal open tubing ends in fluid and pneumatic line systems. Constructed from brass, it provides reliable corrosion resistance in both liquid and air applications. The plug fits tube inside diameters of 0.096 inches by 0.170 inches and is sized for 5/32 inch by 1/4 inch tube outside diameter. The multiple-barb design locks the plug in place once seated, eliminating the need for clamps or adhesives in low-pressure service. This is a single-piece fitting installed by hand or with basic assembly tools.

This fitting is suited for residential and light commercial applications where a tubing branch or line end must be capped and sealed. Common uses include HVAC drain line terminations, pneumatic control tubing, and fluid handling assemblies where a permanent or semi-permanent plug is required. It is compatible with flexible plastic and rubber tubing matching the specified inside diameter range. Plumbers, HVAC technicians, and fluid system assemblers typically stock this style of fitting for field repairs and new installations.
