Value Collection ZMSCV70905 Viton O-ring Dash 905 25-pack

Product Description

The VALUE COLLECTION ZMSCV70905 is a Dash 905 Viton (fluoroelastomer) O-ring designed for use in straight-thread tube fitting boss gasket applications. With a 0.414-inch inside diameter, 0.558-inch outside diameter, and 0.072-inch cross-section thickness, this round-section ring seals reliably against petroleum-based fluids and a wide range of industrial chemicals. Rated at 70 durometer (hard), it delivers low compression set and high-temperature resistance across a working range of -15 degrees F to 400 degrees F. Each package contains 25 rings. Licensed trades and maintenance technicians use these in hydraulic, pneumatic, and fuel-handling assemblies where elastomeric seal integrity is critical.

This O-ring is suited for residential and commercial applications involving petroleum products, fuels, hydraulic oils, and similar media. Its fluoroelastomer compound provides good vacuum service performance and low gas permeability, making it appropriate for plumbing, HVAC refrigerant-adjacent fittings, and light industrial fluid systems that require a durable, chemically compatible face or boss seal. Sold in a 25-piece package, these rings are well-suited for shop stock or field service kits where Dash 905 sizing is a common call-out.

Compatibility

Designed as an O-ring boss gasket for straight-thread tube fittings requiring Dash 905 sizing (0.414 inches ID x 0.558 inches OD x 0.072 inches thick). Compatible with petroleum products and assemblies suited to fluoroelastomer seals. Not FDA approved.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. De-energize and depressurize the system fully before replacing any O-ring seal. Inspect the mating groove and fitting threads for nicks or contamination before seating the new ring. Avoid twisting or pinching the O-ring during assembly, as distortion will compromise the seal.
