Value Collection ZMSCS70024 Silicone O-ring Dash 024 50-pack

Product Description

The VALUE COLLECTION ZMSCS70024 is a round-cross-section silicone O-ring used to create static or dynamic seals in fluid and gas systems across HVAC, plumbing, and industrial applications. It measures 1.125 inches inside diameter, 1.25 inches outside diameter, and 0.0625 inches thick, conforming to Dash 024 sizing. The silicone compound delivers a wide service temperature range of -80 degrees F to 450 degrees F, making it well suited for systems that see extreme thermal cycling or prolonged dry heat exposure. Each order unit contains 50 rings. Licensed tradespeople and maintenance technicians use this ring wherever a Dash 024 silicone seal is specified.

This O-ring is appropriate for residential and light commercial HVAC equipment, plumbing fixtures, and general mechanical assemblies where exposure to wide temperature swings, ozone, or weathering is expected. The silicone material provides good resistance to dry heat and ozone but offers only limited oil resistance, so it should not be substituted into heavy petroleum or aggressive solvent service without verifying compatibility. Typical install locations include valve stems, cap fittings, sensor ports, and access covers in air-handling and water-distribution systems.

Key Features

• Dash 024 standard sizing: 1.125 inches ID, 1.25 inches OD, 0.0625 inches thick
• Silicone compound rated from -80 degrees F to 450 degrees F continuous service
• Round cross section for uniform sealing contact and consistent compression
• Hardness rating of 70 Shore A for a firm, resilient seal under mechanical load
• Good resistance to weathering, ozone, and dry heat; compatible with oils, chemicals, and solvents within rated limits
• Sold in a 50-piece pack to support job-site stocking and service fleet inventories

Compatibility

Designed as a Dash 024 silicone O-ring replacement suitable for any fitting, valve, or port that accepts the standard Dash 024 cross-section profile. Verify groove dimensions and fluid compatibility before installation.

Installation Notes

O-rings in this size range are typically installed by HVAC technicians, plumbers, or industrial maintenance mechanics following manufacturer torque and compression specifications for the mating hardware. De-pressurize and isolate the system completely before removing the old seal. Inspect the groove for burrs or scoring that could damage the new ring. Apply a thin, compatible lubricant to ease installation and reduce the risk of twisting or tearing the ring during assembly.
