Value Collection ZMSCV70207 Viton O-ring Dash 207 Pack of 25

Product Description

The VALUE COLLECTION ZMSCV70207 is a Dash 207 Viton (fluoroelastomer) O-ring used to create static or dynamic fluid seals in plumbing, hydraulic, pneumatic, and HVAC systems. It measures 0.563 inches inside diameter, 0.813 inches outside diameter, and 0.125 inches thick, with a round cross section and a Shore A hardness of 70. The fluoroelastomer compound delivers high temperature resistance up to 400 degrees F and a low minimum working temperature of -15 degrees F, making it suitable for demanding service environments. Licensed tradespeople and maintenance professionals specify this compound where petroleum-based fluids, fuels, or aggressive chemicals are present.

This O-ring is well suited for residential and commercial applications involving petroleum product contact, including fuel lines, hydraulic fittings, refrigeration service valves, and compressor assemblies. The fluoroelastomer formulation resists compression set, maintaining a reliable seal over repeated thermal cycles. It is also rated for vacuum service and exhibits low gas permeability, expanding its utility to refrigerant recovery equipment and vacuum pump connections. Each package contains 25 O-rings, supporting service kits and stock replenishment for plumbing and mechanical shops.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Always relieve system pressure and isolate the fluid supply before removing or replacing O-rings. Lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during assembly. Inspect the gland groove for nicks or corrosion that could compromise the seal before installing a new O-ring.
