Value Collection ZMSCS70152 Silicone O-ring Dash 152

Product Description

The VALUE COLLECTION ZMSCS70152 is a round cross-section silicone O-ring in the standard Dash 152 size, designed for static and dynamic sealing applications across a wide temperature range. It measures 3.25 inches inside diameter, 3.438 inches outside diameter, and 0.0937 inches thick. Rated at 70 durometer (hard), this O-ring is suited for environments requiring dry heat resistance and reliable sealing from -80 degrees F to 450 degrees F. Licensed plumbers, HVAC technicians, and industrial maintenance professionals use silicone O-rings in applications where extreme temperatures or ozone exposure would degrade standard nitrile or EPDM seals.

This O-ring fits sealing applications involving oils, chemicals, and solvents where silicone compounds are compatible. Its wide temperature tolerance makes it a practical choice for HVAC equipment, plumbing components, and general mechanical assemblies that cycle through large temperature swings. Note that silicone has limited oil resistance compared to nitrile compounds, so verify fluid compatibility before installation. Sold in a package quantity of 10.

Key Features

• Round cross-section profile for standard groove fitment

Compatibility

Designed as an OEM-style replacement or maintenance spare for any application requiring a Dash 152 round cross-section O-ring in silicone compound. Verify groove dimensions and fluid compatibility before installation.

Installation Notes

Power down or depressurize the system completely before replacing any O-ring in a pressurized fluid or gas circuit. Lubricate the O-ring with a compatible lubricant prior to seating to prevent tearing or rolling during installation. Do not use petroleum-based lubricants with silicone O-rings unless confirmed compatible with the compound. Follow applicable plumbing or mechanical codes for the system being serviced.
