Value Collection ZMSC55323745 O-ring Kit 611 Pc Nbr

Product Description

The VALUE COLLECTION ZMSC55323745 is a 611-piece nitrile butadiene rubber (NBR) O-ring assortment kit covering 38 different sizes in a single package. NBR is a widely used elastomer for sealing applications involving petroleum-based oils, hydraulic fluids, fuels, and water. The kit is suited for plumbing, HVAC, and general mechanical maintenance work where a technician needs a broad range of O-ring sizes on hand without sourcing individual rings. Each ring provides a reliable static or dynamic seal in standard groove applications across a variety of fittings, valves, and connectors.

This assortment is intended for trade professionals who perform multi-system service calls and need on-hand inventory for common O-ring replacements. Typical applications include valve stem seals, refrigerant line fittings, hydraulic connections, and water supply components. The NBR material performs well in low- to moderate-temperature service environments and is compatible with most petroleum-based lubricants and hydraulic fluids encountered in HVAC, plumbing, and light industrial settings. The 38-size range covers the most frequently encountered standard O-ring dimensions in residential and light commercial work.

Installation Notes

O-ring replacement is performed by licensed plumbers, HVAC technicians, and mechanical service professionals depending on the system involved. Always isolate and de-pressurize the system and shut off any fluid or refrigerant supply before removing or installing O-rings. Lightly lubricate the O-ring with a compatible lubricant prior to seating to reduce the risk of tearing during assembly. Verify the replacement ring matches the original groove dimensions before final assembly.
