Value Collection ZMSCV70327 Viton O-ring Dash 327 Pack 25

Product Description

The VALUE COLLECTION ZMSCV70327 is a Dash 327 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in systems that handle petroleum products, high-temperature fluids, and chemically aggressive media. The ring measures 1.75 inches inside diameter, 2.125 inches outside diameter, and 0.1875 inches (3/16 inches) thick, with a 70-durometer hardness rating. Fluoroelastomer construction delivers low compression set, broad chemical compatibility, and low gas permeability, making this O-ring a reliable choice for vacuum service as well as pressure applications. Each package contains 25 pieces.

This O-ring is suited for use in HVAC refrigeration circuits, plumbing and hydraulic fittings, fuel system connections, and industrial equipment where sealing surfaces contact petroleum-based fluids or operate across wide temperature swings. Its rated operating range of -15 degrees F to 400 degrees F covers most residential and light commercial service environments. Licensed HVAC technicians, plumbers, and industrial maintenance mechanics commonly stock Dash 327 Viton O-rings for routine seal replacements and preventive maintenance kits.

Compatibility

Designed as a standard Dash 327 O-ring replacement for grooves and glands dimensioned to a 1.75-inch ID, 2.125-inch OD, and 3/16-inch cross section per standard O-ring sizing conventions. Compatible sealing media include petroleum products and fluids within the stated temperature range.

Installation Notes

Always depressurize and isolate the system before removing or installing O-rings. Clean the gland groove and mating surfaces of debris, old sealant, and residual fluid before seating the new ring. Apply a thin film of compatible lubricant to the O-ring prior to assembly to ease installation and reduce the risk of tearing or twisting. Follow applicable mechanical and plumbing codes for the system being serviced.
