Value Collection ZMSC31951270 Viton O-ring Kit 500 Pc

Product Description

The VALUE COLLECTION ZMSC31951270 is a 500-piece Viton O-ring assortment kit designed for sealing applications across plumbing, HVAC, and fluid-handling systems. Each ring is molded from Viton fluoroelastic compound at a Shore A durometer rating of 75, placing it in the hard range for reliable compression and long-term sealing under pressure and chemical exposure. Cross sections are round throughout the kit. Inside diameters range from 1.5 to 3 inches, covering multiple thickness groupings to suit a wide variety of fitting and valve sizes. Licensed trades and maintenance technicians working across multiple equipment types will find this kit a practical bench-stock solution.

This kit is suited for residential and light commercial service work where a technician needs on-hand O-ring inventory across multiple sizes. The assortment spans several cross-section thickness groupings: 1.5-inch thickness in sizes 3, 13, and 16; 1.6-inch thickness covering sizes 2.2 through 13.1; and 2-inch thickness in sizes 4 through 24. It is appropriate for use in plumbing valve rebuilds, refrigerant-side HVAC service fittings, and fluid-control components where Viton material compatibility with oils, fuels, and many refrigerants is required.

Compatibility

Designed as a general-purpose replacement O-ring assortment for plumbing valves, HVAC service fittings, and fluid-handling components requiring Viton seals with inside diameters between 1.5 and 3 inches.

Installation Notes

O-ring replacement is typically performed by licensed plumbers, HVAC technicians, or mechanical service technicians. Before servicing any valve, fitting, or pressurized component, shut off the fluid or refrigerant supply and relieve system pressure completely. Inspect the groove for damage or debris before seating the new ring. Avoid twisting or pinching the O-ring during installation, as deformation can cause immediate seal failure.
