Value Collection BD-C562417 Viton O-ring Dash 330

Product Description

The VALUE COLLECTION BD-C562417 is a Viton O-ring sized at 2.125 inches inside diameter and 2.5 inches outside diameter with a cross-section thickness of 0.21 inches (3/16 inches nominal). Classified as Dash 330, this O-ring is molded from Viton fluoroelastic compound at a Shore A durometer of 75, providing firm resistance to compression set. It is rated for continuous service from -15 degrees F to 400 degrees F, making it suitable for high-temperature fluid and gas sealing applications. Plumbers, HVAC technicians, and industrial maintenance mechanics install this type of O-ring as a static or low-cycle dynamic face seal, boss seal, or groove-mounted seal in valves, fittings, pumps, and manifolds.

This O-ring is used in residential and light commercial HVAC systems, plumbing assemblies, hydraulic circuits, and chemical process equipment where petroleum-based lubricants, fuels, or elevated temperatures would degrade standard nitrile or EPDM seals. The Viton compound offers strong resistance to oils, hydraulic fluids, and many organic solvents. It is sold in a package quantity of 10, making it practical for service stock or a multi-unit repair job.

Compatibility

Designed as a Dash 330 standard O-ring replacement for any groove or boss fitting machined to the AS568 Dash 330 cross-section and bore dimensions, commonly found in HVAC valve bodies, plumbing unions, hydraulic fittings, and pump housings requiring a Viton-grade seal.

Installation Notes

Plumbers, HVAC technicians, or industrial mechanics typically install this O-ring. Always depressurize and drain the system before removing the old seal, and clean the groove of debris, old seal material, and corrosion before seating the new ring. Apply a thin film of compatible lubricant to the O-ring before installation to prevent tearing during assembly. Verify that the replacement groove dimensions match Dash 330 specifications before installing to avoid under- or over-compression of the cross-section.
