Value Collection ITRS-10-BKN Tapered Rubber Stopper Size 10

Product Description

The VALUE COLLECTION ITRS-10-BKN is a size 10 tapered rubber stopper used to seal, plug, or cap openings in laboratory glassware, industrial vessels, and fluid-handling equipment. The stopper measures 1-21/32 inches at the small end and 1-31/32 inches at the large end, with a projection of 1.969 inches. It is molded from black rubber with a Shore A durometer hardness range of 38 to 48, giving it enough flexibility to compress and seat firmly into a variety of opening sizes. Plumbers, lab technicians, and industrial maintenance crews use these stoppers for pressure testing, flow isolation, and general plugging tasks.

This stopper suits a wide range of general-purpose plugging and sealing applications where a flexible, tapered fit is required. Common uses include sealing drain lines during hydrostatic pressure tests, capping open pipe ends, and stopperring flasks or carboys in laboratory and light industrial settings. The tapered geometry allows a single stopper to fit a range of opening diameters, reducing the need to stock multiple sizes for similar applications. Sold in a package quantity of eight, making it practical for service vans and shop supply.

Installation Notes

A licensed plumber or qualified technician should isolate and depressurize any line or vessel before inserting or removing a rubber stopper. Insert the stopper small-end first and apply firm, even hand pressure to seat it against the opening walls. Do not use tools that could puncture or deform the rubber. For pressure-test applications, verify that the stopper rating is appropriate for the test pressure before proceeding.
