Value Collection ZMSCV70250 Viton O-ring Dash 250 5pk

Product Description

The VALUE COLLECTION ZMSCV70250 is a Dash 250 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across plumbing, HVAC, and industrial fluid systems. It measures 5 inches inside diameter, 5.25 inches outside diameter, and 0.125 inches thick with a round cross section. The fluoroelastomer compound delivers low compression set, high temperature resistance up to 400 degrees F, and broad chemical compatibility. This O-ring is sold in a package quantity of 5 and is installed by licensed plumbers, HVAC technicians, and mechanical contractors wherever a reliable, heat-tolerant seal is required.

This O-ring suits applications involving petroleum-based fluids, hydraulic oil, fuel systems, and high-temperature fluid handling where standard nitrile or EPDM materials fall short. Its operating range of -15 degrees F to 400 degrees F makes it appropriate for both high-heat process lines and chilled fluid systems. The low gas permeability characteristic also makes it suitable for vacuum service applications. Typical install scenarios include pump housings, valve bodies, manifold connections, and refrigerant system fittings that call for a Dash 250 cross-section seal.

Key Features

• Fluoroelastomer (Viton-type) compound with good resistance to petroleum products
• Operating temperature range: -15 degrees F to 400 degrees F
• Round cross section with low compression set for reliable long-term sealing
• Suitable for vacuum service and exhibits low gas permeability
• Hard hardness rating (70 durometer) for dimensional stability under compression
• Wide spectrum of chemical compatibility including petroleum-based fluids

Compatibility

Designed as a Dash 250 standard O-ring replacement compatible with systems and components that require a 5-inch ID fluoroelastomer seal, particularly those involving petroleum products and high-temperature fluid service.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. De-pressurize and drain or isolate the fluid circuit completely before removing the old O-ring and installing the replacement. Inspect the mating groove for damage, burrs, or debris before seating the new O-ring. Lubricate the O-ring with a compatible fluid or grease before installation to prevent tearing and ensure proper seating; do not use petroleum-based lubricants with non-compatible elastomers.
