Parker PP-00857 Nylon Sleeve Packing 1.81 in Id

Product Description

The PARKER PP-00857 is a nylon sleeve packing designed to provide a reliable sealing solution in fluid handling and mechanical assemblies. With an inside diameter of 1.81 inches and a black nylon construction, this sleeve packing is suited for applications requiring a durable, low-friction seal material. Nylon offers good resistance to wear, moderate chemical exposure, and repeated mechanical cycling. Licensed tradespeople in plumbing, HVAC, and industrial maintenance install this type of packing to maintain system integrity at shaft seals, valve stems, and similar dynamic or static sealing points.

This sleeve packing is appropriate for residential and light commercial plumbing, HVAC, and general mechanical service applications where a 1.81-inch inside diameter is required. It is typically used in pump shafts, valve assemblies, and similar components that require a fitted sleeve or packing insert. The black nylon material suits environments with moderate fluid exposure and temperature ranges common to water supply and HVAC hydronic systems.
