Value Collection ZMSCS70127 Silicone O-ring Dash 127

Product Description

The VALUE COLLECTION ZMSCS70127 is a silicone O-ring with a round cross section, sized to Dash 127 standards with a 1.438-inch inside diameter, 1.625-inch outside diameter, and 0.094-inch thickness. Rated at 70 durometer (hard), this O-ring is designed for static and dynamic sealing applications where a wide temperature range and reliable dry heat resistance are required. Silicone compound provides good ozone and weather resistance, making it a dependable choice for maintenance, repair, and OEM applications across HVAC, plumbing, and general industrial settings. Each package contains 25 O-rings. Licensed tradespeople and maintenance technicians commonly stock these for routine seal replacement work.

This O-ring is suited for residential and light commercial applications where the sealing environment involves exposure to oils, chemicals, or solvents at moderate levels. The wide service temperature range of -80 degrees F to 450 degrees F makes it appropriate for both heating-side and cooling-side components, as well as general mechanical assemblies requiring a durable elastomeric seal. It is not FDA approved and should not be used in food-contact or potable water applications without verifying local code compliance.

Compatibility

Designed as a Dash 127 standard O-ring replacement for any groove or port machined to accommodate a 1.438-inch ID, 1.625-inch OD, 0.094-inch cross section seal in silicone material.

Installation Notes

O-ring installation should be performed by a qualified technician familiar with the equipment being serviced. Always de-energize, depressurize, and drain the system before replacing any seal. Inspect the O-ring groove for burrs, corrosion, or debris before seating the new O-ring, and apply a compatible lubricant to ease installation and reduce the risk of tearing. Do not stretch the O-ring beyond its rated dimensions during installation.
