Ever-tite 310GSKVA Viton O-ring Dash 310 Square Cross Section

Product Description

The EVER-TITE COUPLING PRODUCTS 310GSKVA is a Viton square-cross-section O-ring designed for static and dynamic sealing applications across a wide range of fluid and chemical service conditions. With an inside diameter of 1.062 inches, an outside diameter of 1.562 inches, and a thickness of 0.25 inches, this Dash 310 O-ring meets standard AN6227 and MS28775 sizing conventions. The Viton (FKM) compound delivers a working temperature range of -15 degrees F to 450 degrees F, making it suitable for high-heat environments where standard nitrile or neoprene seals would degrade. The square cross section increases sealing contact area compared to a round-profile ring, reducing the chance of blowout under pressure cycling.

This O-ring is commonly installed in hydraulic systems, fuel delivery assemblies, HVAC refrigerant circuits, plumbing fittings, and chemical processing equipment. Its Viton compound is rated compatible with mineral oils, fuels, hydraulic fluids, organic solvents, and a broad range of industrial chemicals. It is sold as a single unit and is appropriate for use by licensed plumbers, HVAC technicians, hydraulic system technicians, and industrial maintenance professionals working on fluid-handling assemblies requiring a Dash 310 seal.

Key Features

• Viton (FKM) compound resists degradation from fuels, hydraulic fluids, mineral oils, and organic solvents
• Square cross section increases contact surface area for a more robust seal under pressure cycling
• Wide service temperature range: -15 degrees F to 450 degrees F
• Dash 310 standard sizing: 1.062 inches ID x 1.562 inches OD x 0.25 inches thick
• Black color for easy visual identification in mixed-material seal kits

Compatibility

Compatible with systems and assemblies that handle mineral oil, fuels, hydraulic fluid, and organic solvents and chemicals. Designed as a Dash 310 standard-size O-ring for use in any fitting, port, or housing machined to accept that nominal size.

Installation Notes

Installation should be performed by a qualified technician familiar with fluid-system sealing procedures. Depressurize and drain the affected system completely before removing the existing seal. Inspect the mating groove for nicks, scoring, or contamination that could compromise the new seal. Avoid rolling or twisting the O-ring during installation; seat it flat in the groove without stretching it beyond its nominal diameter.
