Value Collection ZMSCA80020 Aflas O-ring Dash 020

Product Description

The VALUE COLLECTION ZMSCA80020 is an Aflas O-ring with a 0.875-inch inside diameter, 1-inch outside diameter, and a 0.0625-inch cross-section thickness. Aflas is a fluoroelastomer compound known for its resistance to high temperatures, ozone, and a broad range of aggressive fluids. Rated at an 80 durometer hardness with a working temperature range of 25 degrees F to 450 degrees F, this O-ring delivers reliable sealing performance in demanding service environments. It is installed by HVAC technicians, plumbers, and mechanical contractors in applications requiring a durable elastomeric seal against chemicals, refrigerants, and hydraulic media.

This O-ring is suited for use in HVAC refrigeration systems, hydraulic assemblies, fuel systems, and plumbing connections where exposure to aggressive chemicals or wide temperature swings is expected. Compatible materials listed by the manufacturer include acetic acid, animal oils, bases, brake fluids, fuels, and hydraulic oil. Its Aflas compound also provides excellent sealing performance with refrigeration fluids. Sold in a package quantity of 10, this ring is a standard Dash 020 size for ease of cross-referencing to existing specifications.

Installation Notes

O-rings should be installed by a qualified technician following applicable system lockout and pressure-relief procedures before disassembly. Ensure the seating groove is clean and free of burrs before installing. Do not overstretch the ring during installation, as Aflas compound has limited elongation compared to nitrile or EPDM elastomers. Consult applicable mechanical or refrigeration codes for torque and fitting assembly requirements.
