Value Collection ZMSCV70323 Viton O-ring Dash 323 10 Pack

Product Description

The VALUE COLLECTION ZMSCV70323 is a Dash 323 Viton O-ring designed for sealing applications that demand resistance to high temperatures, petroleum-based fluids, and a wide range of chemicals. Manufactured from fluoroelastomer with a Shore A hardness of 70, this O-ring features a round cross section measuring 1.313 inches ID, 1.688 inches OD, and 0.1875 inches thick. Rated for continuous service from -15 degrees F to 400 degrees F, it is well suited for environments where standard nitrile or EPDM compounds fall short. Each package contains 10 O-rings.

This O-ring is used in HVAC, refrigeration, plumbing, and industrial fluid-handling systems where petroleum product exposure, vacuum service, or elevated operating temperatures are common. Typical applications include valve stems, pump shafts, fittings, and manifold connections in both residential and light commercial equipment. Its low gas permeability makes it a practical choice for vacuum service and sealed fluid circuits. Licensed HVAC technicians, plumbers, and industrial mechanics are the primary installers.

Key Features

• Fluoroelastomer (Viton) compound provides broad chemical compatibility and high-temperature resistance up to 400 degrees F
• Low compression set maintains seal integrity under sustained clamping loads
• Suitable for petroleum product exposure including oils, fuels, and hydraulic fluids
• Low gas permeability supports vacuum service applications
• Round cross section for consistent seating in standard O-ring grooves
• Shore A hardness of 70 rated as Hard for reliable sealing under pressure

Compatibility

Designed as a Dash 323 replacement O-ring compatible with petroleum products and systems requiring fluoroelastomer seals; verify groove dimensions against ID of 1.313 inches, OD of 1.688 inches, and cross-section thickness of 0.1875 inches before installation.

Installation Notes

Power down or depressurize the system and relieve all residual pressure before replacing any O-ring. Lubricate the O-ring with a compatible fluid or assembly lubricant prior to installation to prevent tearing during seating. Do not overstretch the O-ring during installation; use proper O-ring picks or tools rather than sharp instruments. Verify groove dimensions and surface finish meet manufacturer specifications to ensure a proper seal.
