Value Collection ZMSCV70918 Viton O-ring Dash 918 25-pack

Product Description

The VALUE COLLECTION ZMSCV70918 is a Dash 918 Viton O-ring designed for sealing applications that demand resistance to high temperatures, petroleum-based fluids, and a wide range of chemicals. Manufactured from fluoroelastomer (Viton) with a Shore 70 hardness, this O-ring maintains a reliable seal from -15 degrees F to 400 degrees F. The round cross-section profile measures 1.355 inches inside diameter, 1.587 inches outside diameter, and 0.116 inches thick. It is commonly installed by HVAC technicians, plumbers, and hydraulic system mechanics who require a durable, low-compression-set seal in demanding service environments.

This O-ring is specified as an O-Ring Boss (ORB) gasket for straight-thread tube fittings. It is well-suited for applications involving petroleum products, hydraulic systems, fuel lines, and vacuum service. The low gas permeability characteristic makes it appropriate for sealed pneumatic and vacuum assemblies. Each package contains 25 O-rings, supporting bench stock, service kits, or field inventory needs for maintenance shops and service contractors.

Compatibility

Designed as an O-Ring Boss gasket for straight-thread tube fittings requiring a Dash 918 O-ring in fluoroelastomer or Viton material. Compatible with petroleum-based fluids and systems per manufacturer specification.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Before replacing the O-ring, depressurize the system completely and isolate all fluid supply. Ensure the seating groove is clean and free of debris or old elastomer before installing the new ring. Lightly lubricating the O-ring with a compatible fluid or grease prior to installation helps prevent tearing and ensures proper seating.
