Value Collection ZMSCV70127 Viton O-ring Dash 127

Product Description

The VALUE COLLECTION ZMSCV70127 is a Dash 127 Viton fluoroelastomer O-ring designed for sealing applications that demand resistance to high temperatures and petroleum-based fluids. It measures 1.438 inches inside diameter, 1.625 inches outside diameter, and 0.094 inches (3/32 inches) thick with a round cross section. Rated at 70 Shore A hardness, this O-ring handles continuous service from -15 degrees F to 400 degrees F. The fluoroelastomer compound offers low compression set, good vacuum service performance, and low gas permeability. Each package contains 25 O-rings.

This O-ring is suited for use in HVAC, plumbing, hydraulic, pneumatic, and refrigeration systems where exposure to petroleum products, oils, fuels, or elevated temperatures is expected. The Dash 127 designation is a standard AS568 size, making it a common fit across a wide range of industrial and trade service applications. Installers use these in valve stems, pump seals, fittings, and fluid-system connections where a reliable static or dynamic seal is required.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or hydraulic system mechanics. Depressurize and de-energize the system completely before replacing any O-ring. Inspect the seating groove for damage or debris before installation, and lightly lubricate the O-ring with a compatible fluid or grease to prevent twisting or tearing during assembly. Avoid overstretching the O-ring during placement.
