StockCap now provides two styles of its Rubber Seal Plugs sized to fit standard copper tube dimensions. The plugs include a press-fit feature, which the company says makes the insertion of the plug into the tube easy. Also, a self-sealing material allows for the injection of gas into the plugged tube, keeping it clean and dry during shipment and storage. These plugs protect and seal tubing used in various applications including HVAC components and tubing for medical use. A variety of sizes in varying lengths and diameters are available. Black is the standard color, but the company also has a variety of custom colors. Free samples are available by contacting the company.
