Value Collection ZMSCV70236 Viton O-ring Dash 236 10 Pack

Product Description

The VALUE COLLECTION ZMSCV70236 is a Dash 236 Viton (fluoroelastomer) O-ring used to create fluid-tight and gas-tight seals in mechanical assemblies, piping connections, and equipment used in HVAC, plumbing, and industrial service. It measures 3.25 inches inside diameter, 3.5 inches outside diameter, and 0.125 inches thick with a round cross-section. The fluoroelastomer compound delivers a working temperature range of -15 degrees F to 400 degrees F, making it well suited for high-heat and chemically demanding environments. Hardness is rated at 70 Shore A. This O-ring is sold in a package of 10.

This O-ring is intended for use in systems where exposure to petroleum products, hydraulic fluids, or elevated temperatures would degrade standard nitrile or EPDM seals. Typical applications include pump housings, valve bodies, refrigeration fittings, and fluid-handling equipment in residential and commercial mechanical systems. The low compression set and low gas permeability characteristics make it a practical choice for vacuum service and pressure-containing assemblies where seal integrity is critical over extended service intervals.

Key Features

• Fluoroelastomer (Viton) compound rated for service from -15 degrees F to 400 degrees F
• 70 Shore A hardness with hard hardness rating for stable compression under load
• Round cross-section, Dash 236 standard sizing for straightforward groove compatibility
• Good resistance to petroleum products, hydraulic fluids, and a wide spectrum of chemicals
• Low gas permeability makes it suitable for vacuum service applications
• Packaged in quantities of 10 for bench stock and service van inventory

Compatibility

Designed as a standard Dash 236 O-ring replacement suitable for any groove or fitting machined to Dash 236 dimensions where a fluoroelastomer compound is specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Always depressurize and isolate the system before removing or replacing O-rings, and verify the groove is clean and free of debris or damage prior to installation. Lubricate the O-ring with a compatible fluid or grease before seating to prevent rolling or tearing during assembly. Do not stretch the O-ring beyond the minimum required to seat it in the groove.
