Ever-tite. Coupling Products 315GSKVA Viton O-ring

Product Description

The EVER-TITE. COUPLING PRODUCTS 315GSKVA is a Viton square cross-section O-ring designed for sealing applications in industrial, hydraulic, and fluid-handling systems. With an inside diameter of 1.625 inches, an outside diameter of 2.218 inches, and a thickness of 0.25 inches, this Dash 315 O-ring provides a reliable static or dynamic seal where chemical resistance and wide temperature tolerance are required. The square cross-section geometry increases the sealing contact area compared to a round profile, making it well suited for groove applications that demand consistent compression. Licensed tradespeople and maintenance technicians working on hydraulic assemblies, fuel systems, and chemical-handling equipment rely on this ring for dependable long-term sealing performance.

This O-ring is appropriate for use in residential and commercial maintenance scenarios involving mineral oil systems, hydraulic fluid circuits, fuel handling lines, and organic solvent environments. Its Viton material makes it a preferred choice when standard nitrile rings are inadequate due to elevated temperatures or aggressive chemical exposure. It is commonly installed in pump housings, valve bodies, flange connections, and manifold fittings where the groove dimensions correspond to a Dash 315 specification.

• Lightweight construction at 0.029 pounds per unit

Compatibility

Compatible with systems using mineral oil, fuels, hydraulic fluid, and organic solvents and chemicals. Fits any Dash 315 groove specification with an inside diameter of 1.625 inches, outside diameter of 2.218 inches, and thickness of 0.25 inches.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with hydraulic or fluid-sealing systems. Always depressurize and lock out the system before removing or replacing any O-ring. Inspect the groove for burrs, corrosion, or wear before seating the new ring, and apply a compatible lubricant to ease installation and prevent damage to the sealing surface. Do not roll or twist the O-ring during installation, as distortion can cause premature seal failure.
