Value Collection KP77917 Pressure Sealing Washers 10-pack

Product Description

The VALUE COLLECTION KP77917 is a pressure sealing washer designed to create a reliable seal under compression in bolted or fastened assemblies. Each washer combines a neoprene sealing element with a steel backing to handle mechanical load while maintaining a fluid or air-tight seal at the joint face. These washers are used in plumbing, HVAC, and general mechanical applications where standard flat washers would allow leakage past the fastener. The package contains 10 washers. Installation requires no special tools and the washers are compatible with standard bolt and screw hardware found in trade service work.

Pressure sealing washers of this type are commonly installed in residential and light commercial systems wherever a fastener passes through a surface exposed to fluid pressure or environmental moisture. Typical applications include pipe flanges, access panels, equipment enclosures, and sheet metal assemblies. The neoprene layer conforms to surface irregularities to fill small gaps, while the steel shell distributes clamping load evenly across the sealing face. Service technicians across plumbing, HVAC, and mechanical trades install these as part of routine maintenance and new equipment assembly.

Key Features

• Neoprene sealing element resists water, oils, and mild chemicals common in HVAC and plumbing environments
• Steel backing distributes bolt load and prevents over-compression of the neoprene
• Designed for use in bolted assemblies requiring a pressure-tight seal at the fastener
• Sold in a convenient 10-piece pack for stocking and service truck use
• Compatible with standard bolt and screw hardware without special tooling

Compatibility

Designed as a general-purpose pressure sealing washer for use in bolted and fastened assemblies across plumbing, HVAC, and mechanical trade applications where a fluid or air-tight seal at the fastener is required.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or mechanical tradespeople as part of bolted assembly work. Always depressurize and de-energize the system before servicing any joint or fastener. Ensure the mating surface is clean and free of debris before seating the washer to allow proper neoprene contact. Do not over-torque the fastener, as excessive clamping force can damage the neoprene element and compromise the seal.
