Value Collection V90902 Fluoroelastomer O-ring 90 Duro

Product Description

The VALUE COLLECTION V90902 is a fluoroelastomer O-ring designed for sealing applications that demand resistance to high temperatures, petroleum-based fluids, and a wide range of chemicals. With a 90-durometer extra-hard rating, this O-ring maintains its shape under compression in demanding service conditions. It features a round cross section measuring 0.125 inches and an inside diameter of 0.239 inches. Rated for continuous service from -15 degrees F up to 400 degrees F, it is suited for HVAC, plumbing, fuel-handling, and light industrial assemblies where standard rubber compounds would degrade prematurely.

This O-ring is used as a static or dynamic seal in systems handling petroleum products, hydraulic fluids, and chemicals incompatible with standard nitrile or EPDM compounds. Typical applications include fuel-line fittings, valve seats, pump housings, and refrigeration service ports. It is also appropriate for vacuum service applications due to its low gas permeability. Technicians in HVAC, plumbing, and mechanical trades install this O-ring during routine maintenance, valve rebuilds, and equipment overhauls where a high-temperature-rated seal is required.

Key Features

• Fluoroelastomer construction provides broad chemical compatibility, including petroleum products
• 90-durometer extra-hard rating for low compression set under sustained load
• Operating temperature range of -15 degrees F to 400 degrees F
• Low gas permeability makes it suitable for vacuum service applications
• Round cross section ensures consistent sealing contact in standard O-ring grooves
• Black color; non-FDA-approved material

Compatibility

Designed as a replacement or service O-ring for sealing assemblies that specify a fluoroelastomer compound with a 0.239-inch inside diameter and 0.125-inch cross section, particularly where petroleum product exposure or elevated temperatures are present.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Always depressurize and de-energize the system before removing any sealed component. Inspect the O-ring groove for damage or debris before installing the new seal, and avoid over-stretching the O-ring during placement. Do not use petroleum-based lubricants on O-ring materials unless confirmed compatible with fluoroelastomer compounds.
