Value Collection ZMSCS70135 Silicone O-ring Dash 135

Product Description

The VALUE COLLECTION ZMSCS70135 is a round-cross-section silicone O-ring sized to Dash 135 dimensions, with a 1.938-inch inside diameter, 2.125-inch outside diameter, and a 3/32-inch (0.0937-inch) wall thickness. Rated at 70 durometer on the hardness scale, this O-ring is manufactured from silicone compound that handles a working temperature range of -80 degrees F to 450 degrees F. It is sold in packs of 10 and is appropriate for use by licensed plumbers, HVAC technicians, and industrial maintenance professionals who need a reliable static or dynamic seal in high- or low-temperature environments.

This O-ring is suited for applications that demand wide temperature tolerance and good dry heat resistance. Silicone compound also provides good resistance to weathering and ozone exposure. Typical install scenarios include sealing flanges, fittings, valves, and connections in HVAC equipment, fluid handling systems, and light chemical service where limited oil contact is expected. The white color and round cross-section geometry make it straightforward to seat in standard Dash 135 grooves without additional modification.

Key Features

Compatibility

Designed as a standard Dash 135 replacement O-ring for use in any application accepting a 1.938-inch ID, 2.125-inch OD, 3/32-inch cross-section silicone seal. Confirm groove dimensions and chemical compatibility with the specific fluid or gas being sealed before installation.

Installation Notes

Shut off and depressurize the system before removing or replacing any O-ring. Clean the groove and mating surfaces of debris, old sealant, and residual compound before seating the new ring. A thin film of compatible lubricant may aid installation and prevent tearing during assembly — confirm lubricant compatibility with silicone material. Follow applicable plumbing or mechanical codes for the jurisdiction and system type.
