Value Collection ZMSCS70122 Silicone O-ring Dash 122 50 Pack

Product Description

The VALUE COLLECTION ZMSCS70122 is a round cross-section silicone O-ring sized to Dash 122 standards, with a 1.125-inch inside diameter, 1.313-inch outside diameter, and a 0.0937-inch wall thickness. Rated for a wide service temperature range of -80 degrees F to 450 degrees F, this O-ring is formulated for applications demanding reliable sealing under extreme heat or cold. The 70-durometer silicone compound provides hard, stable compression set resistance and good dry heat performance. It is typically installed by plumbers, HVAC technicians, and industrial maintenance professionals in sealing and gasketing applications across fluid, pneumatic, and thermal system assemblies.

This O-ring is suited for residential and light commercial plumbing, HVAC equipment, and general industrial sealing where wide temperature range performance is required. Silicone compound offers good weather and ozone resistance, making it a practical choice for outdoor or exposed equipment. It carries limited oil resistance, so it should not be specified in applications with prolonged hydrocarbon fluid contact. Each package contains 50 O-rings, appropriate for service stock or recurring maintenance use.

Installation Notes

Depressurize and isolate the system before removing the existing O-ring and inspecting the seating groove for damage or debris. Lubricate the O-ring with a compatible silicone-based lubricant before seating to prevent tearing during assembly. Do not use petroleum-based lubricants with silicone compounds, as they may degrade the material over time. Follow applicable codes such as the IPC or IFGC for plumbing and gas system O-ring replacement procedures.
