Value Collection ZMSCS70914 Silicone O-ring Dash 914 25 Pack

Product Description

The VALUE COLLECTION ZMSCS70914 is a Dash 914 silicone O-ring designed for straight-thread tube fitting applications, functioning as an O-Ring Boss (ORB) gasket to create a pressure-tight seal at threaded port connections. The ring measures 1.47 inches inside diameter with a 0.116-inch round cross section and is molded from silicone compound at a Shore A hardness of 70. Silicone material delivers a working temperature range of -80 to 450 degrees F, making it well suited for systems that cycle through wide thermal extremes or operate in sustained dry heat environments. Licensed plumbers, HVAC technicians, and fluid-system assemblers install this ring type as a standard component in ORB port connections across hydraulic, pneumatic, and process piping assemblies.

This O-ring is intended for applications that demand wide temperature tolerance, good weather and ozone resistance, and moderate dry-heat resistance. It is appropriate for use with straight-thread tube fittings in residential and commercial HVAC, plumbing, and general fluid conveyance systems where silicone elastomers are compatible with the process media. Note that silicone carries limited resistance to petroleum-based oils and fuels; confirm media compatibility before installation. Each package contains 25 rings.

Designed as an OEM-style replacement or service-stock O-ring for straight-thread (ORB) tube fitting ports requiring a Dash 914 silicone seal.

Installation Notes

Turn off and depressurize the system completely before removing or installing any O-ring in a pressurized fitting or port. Inspect the seating surface for nicks, corrosion, or debris that could prevent a proper seal; clean the groove before installation. Lightly lubricate the O-ring with a silicone-compatible lubricant to ease installation and reduce the risk of twisting or cutting the ring during assembly. Confirm that silicone elastomer is compatible with the process fluid before torquing the fitting to specification.
