Value Collection ZMSCV70920 Viton O-ring Dash 920 25 Pack

Product Description

The VALUE COLLECTION ZMSCV70920 is a Dash 920 Viton O-ring used to create a reliable fluid-tight or gas-tight seal in straight-thread tube fitting connections, commonly known as O-ring boss (ORB) installations. Made from fluoroelastomer (FKT/Viton), this O-ring measures 1.475 inches inside diameter, 1.711 inches outside diameter, and 0.118 inches thick with a round cross section. It carries a hardness rating of 70 Shore A, which places it in the hard range and makes it well-suited for applications requiring low compression set and resistance to elevated temperatures up to 400 degrees F. Licensed plumbers, HVAC technicians, and hydraulic system mechanics install these seals during fitting assembly and preventive maintenance.

This O-ring is designed for use in systems that handle petroleum products, hydraulic fluids, and a wide spectrum of chemical media. Its fluoroelastomer compound provides good resistance to fuel, oil, and solvent exposure. The low gas permeability characteristic also makes it appropriate for vacuum service applications. It performs across a temperature range of -15 degrees F to 400 degrees F, supporting use in both residential and light commercial plumbing, HVAC refrigerant-adjacent fittings, and industrial fluid-power systems where ORB-style straight-thread fittings are standard. Each package contains 25 O-rings, making it a practical quantity for service trucks and shop stock. This item is not FDA approved and is not intended for food-contact applications.

Compatibility

Specified as an O-ring boss gasket for straight-thread tube fittings using the Dash 920 standard size. Compatible with systems handling petroleum products and media within the chemical resistance profile of fluoroelastomer compounds.

Installation Notes

Installation is performed by a licensed plumber, HVAC technician, or hydraulic system mechanic depending on the application. Depressurize and drain the system completely before removing or installing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating it in the groove to prevent cutting or rolling during tightening. Do not reuse O-rings that show signs of compression set, cracking, or deformation.
