Value Collection ZMSCS70025 Silicone O-ring Dash 025

Product Description

The VALUE COLLECTION ZMSCS70025 is a round-cross-section silicone O-ring sized at 1.188 inches inside diameter, 1.313 inches outside diameter, and 0.0625 inches thick. It carries a Dash 025 designation and a 70 durometer hardness rating. Silicone compound gives this O-ring a wide operating temperature range of -80 degrees F to 450 degrees F, making it appropriate for static or dynamic sealing applications where extreme heat or cold resistance is required. Plumbers, HVAC technicians, and industrial maintenance professionals use this O-ring type as a sealing element in fluid and gas connections.

This O-ring is suited for use in residential and commercial plumbing, HVAC equipment, and general industrial assemblies where the sealing surface contacts oils, chemicals, or solvents within the temperature limits of the silicone compound. Its good weather and ozone resistance makes it a practical choice for outdoor or exposed installations. The white silicone material also performs well in dry-heat environments such as exhaust-adjacent fittings or heating equipment housings. Sold in a package quantity of 50, it is a stock item for shops servicing high volumes of similar connections.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial mechanic. Shut off and depressurize the system completely before removing the existing O-ring or disassembling any fitting. Inspect the seating groove for damage, burrs, or debris before installing the new O-ring. Do not overstretch the O-ring during installation, and confirm the groove dimensions match the Dash 025 profile before seating.
