Value Collection ZMSCV70025 Viton O-ring Dash 025 50-pack

Product Description

The VALUE COLLECTION ZMSCV70025 is a Dash 025 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications in HVAC, plumbing, refrigeration, and fluid-handling systems. It measures 1.188 inches inside diameter, 1.313 inches outside diameter, and 0.0625 inches thick with a round cross section. The fluoroelastomer compound delivers a Shore hardness of 70, handles continuous service from -15 degrees F to 400 degrees F, and resists petroleum-based fluids with low gas permeability. Sold in a package of 50, this SKU is suitable for shops and field techs who stock O-rings by dash size.

This O-ring is used wherever a standard Dash 025 seal is specified — including valve stems, refrigerant fittings, hydraulic connections, fuel system components, and pump housings. Its high-temperature fluoroelastomer construction makes it a practical choice for applications involving petroleum products, oils, and hydraulic fluids. The round cross section seats cleanly into standard O-ring grooves machined to AS568 Dash 025 dimensions. Residential and light-commercial HVAC techs, plumbers, and industrial maintenance professionals all use this dash-size in routine service work.

Installation Notes

O-ring installation should be performed by a qualified HVAC technician, plumber, or maintenance professional familiar with sealing system requirements. Always de-pressurize and isolate the system before removing the existing seal and inspect the groove for nicks or corrosion that could cause leak paths. Apply a compatible lubricant to the O-ring before seating to prevent twisting or pinching during assembly. Do not stretch the O-ring beyond its design limits or use tools that could cut or nick the sealing surface.
