Value Collection ZMSCV70205 Viton O-ring Dash 205 25-pack

Product Description

The VALUE COLLECTION ZMSCV70205 is a Dash 205 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in fluid and gas systems. With an inside diameter of 0.438 inches, an outside diameter of 0.688 inches, and a cross-section thickness of 0.125 inches, this O-ring fits standard Dash 205 grooves. The fluoroelastomer compound delivers a working temperature range of -15 degrees F to 400 degrees F, good resistance to petroleum products, low compression set, and low gas permeability. Each package contains 25 O-rings. This part is commonly installed by HVAC technicians, plumbers, and mechanical service professionals wherever a reliable elastomeric seal is required.

This O-ring is suited for use in residential and commercial systems where petroleum-based fluids, hydraulic media, or high-temperature service conditions are present. Typical applications include refrigeration service valves, hydraulic fittings, fuel system connections, and pump assemblies. The round cross-section profile seats consistently in standard AN and SAE O-ring grooves. The hard durometer rating supports use in higher-pressure sealing scenarios where softer compounds would extrude. Compatible with vacuum service applications due to the low gas permeability of the fluoroelastomer material.

Key Features

• Fluoroelastomer (Viton-type) compound with wide chemical compatibility including petroleum products
• Temperature range of -15 degrees F to 400 degrees F for high-heat service environments
• Low compression set maintains long-term sealing force under sustained load
• Low gas permeability makes this O-ring suitable for vacuum service
• Hard durometer rating resists extrusion in pressurized groove applications
• Sold in a pack of 25 for service stock and repeat-application use

Compatibility

Designed as an OEM-style replacement or service O-ring for Dash 205 groove applications in HVAC, plumbing, hydraulic, and fuel system equipment. Compatible with petroleum products and a wide spectrum of chemical media as noted by the fluoroelastomer compound.

Installation Notes

Shut off and isolate the system from pressure or vacuum before removing any fitting or valve assembly containing this O-ring. Clean the groove thoroughly and inspect for damage or scoring before seating the new O-ring. A thin film of compatible lubricant appropriate to the media being sealed may be applied to ease installation and prevent initial dry-seating damage. Follow applicable system codes and manufacturer torque guidance for the fitting being reassembled.
