Value Collection ZMSCV70325 Viton O-ring Dash 325

Product Description

The VALUE COLLECTION ZMSCV70325 is a Dash 325 Viton (fluoroelastomer) O-ring used to create fluid-tight seals in hydraulic, pneumatic, and process piping systems. It measures 1.5 inches inside diameter, 1.875 inches outside diameter, and 0.1875 inches thick with a round cross section. The 70 durometer hardness rating makes it suited for applications that demand a firm, low-compression-set seal under sustained pressure. Temperature range spans -15 degrees F to 400 degrees F, making it a reliable choice where standard nitrile O-rings would degrade. Licensed plumbers, HVAC technicians, and maintenance mechanics commonly specify Viton seals wherever petroleum-based fluids or elevated heat are present.

This O-ring is appropriate for use in residential and commercial plumbing assemblies, HVAC refrigerant and oil circuits, fuel handling equipment, vacuum service lines, and general industrial fittings that contact petroleum products or aggressive media. Its wide chemical compatibility and low gas permeability make it a preferred elastomer in demanding service environments. The part is sold in packages of 25 units, which suits service contractors maintaining inventory for recurring seal replacements.

Key Features

• Fluoroelastomer (Viton) construction offers high resistance to petroleum products and aggressive chemicals
• 70 durometer hardness provides a firm, low-compression-set seal for sustained-load applications
• Operating temperature range of -15 degrees F to 400 degrees F for high-heat service environments
• Round cross section, Dash 325 standard sizing for drop-in replacement compatibility
• Suited for vacuum service with low gas permeability
• Package quantity of 25 units supports shop stock and recurring maintenance programs

Compatibility

Designed as a standard Dash 325 O-ring replacement for any fitting or component that accepts a 1.5 inches ID by 1.875 inches OD by 0.1875 inches thick round-cross-section seal, particularly in systems that contact petroleum products or operate at elevated temperatures where fluoroelastomer compound is specified.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance mechanics. Always depressurize and drain the system before removing the old seal to prevent fluid release or injury. Inspect the groove for nicks, burrs, or corrosion before seating the new O-ring, and apply a compatible lubricant to help the ring seat without rolling or twisting. Do not stretch the O-ring beyond its rated inside diameter during installation.
