Value Collection BD-C562342 Viton O-ring Dash 243 5-pack

Product Description

The VALUE COLLECTION BD-C562342 is a Dash 243 Viton O-ring designed for static and dynamic sealing applications in fluid and gas systems. It measures 4-1/8 inches inside diameter, 4-3/8 inches outside diameter, and 1/8 inches thick, with a round cross-section profile. The ring is molded from Viton (fluoroelastomer) compound rated at 75 Shore A durometer, making it well suited for environments involving fuels, oils, hydraulic fluids, and elevated temperatures where standard nitrile or EPDM compounds fall short. Each package contains 5 rings. Plumbers, HVAC technicians, and industrial maintenance professionals use this ring in pump housings, valve bodies, and pipe fittings.

This Dash 243 O-ring fits applications calling for an inch-system seal in larger-bore connections where chemical resistance and heat tolerance are priorities. Typical install scenarios include pump seal replacements, large-diameter valve bonnets, and fluid system housings in commercial HVAC, refrigeration, and plumbing systems. Its Viton compound holds dimensional stability across a wide service temperature range, reducing the likelihood of early compression set compared to general-purpose elastomers.

Key Features

• Viton (fluoroelastomer) construction offers resistance to fuels, oils, and hydraulic fluids
• 75 Shore A durometer provides firm sealing under compression without excessive hardness
• Round cross-section for consistent seating in standard O-ring grooves
• Dash 243 sizing conforms to inch-system O-ring standards for straightforward replacement sourcing
• Sold in a package of 5 rings to support service stock or multi-unit jobs

Compatibility

Designed as a standard inch-system Dash 243 O-ring replacement suitable for pump housings, valve bodies, and fluid system components requiring a 4-1/8 inch ID seal with Viton compound compatibility.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical maintenance professionals. Shut off and depressurize the system fully before removing any sealed components. Clean the O-ring groove and mating surfaces of debris or old elastomer material before seating the new ring. Avoid using sharp tools that can nick or cut the ring during installation, as surface damage compromises the seal.
