Value Collection ZMSCV70201 Viton O-ring Dash 201 25-pack

Product Description

The VALUE COLLECTION ZMSCV70201 is a Dash 201 Viton (fluoroelastomer) O-ring sold in a pack of 25. It features a round cross section with an inside diameter of 0.188 inches, an outside diameter of 0.438 inches, and a thickness of 0.125 inches. The fluoroelastomer compound delivers a hardness rating of 70 Shore A, a minimum working temperature of -15 degrees F, and a maximum working temperature of 400 degrees F. These O-rings are suited for static and dynamic sealing applications where exposure to petroleum products, high heat, or a wide range of chemicals is expected. Licensed plumbers, HVAC technicians, and mechanical contractors install these as sealing elements in hydraulic, pneumatic, and fluid-handling systems.

This O-ring is well matched to applications involving petroleum-based fluids, fuels, oils, and hydraulic media. The fluoroelastomer material provides low gas permeability, making it a practical choice for vacuum service and low-emission sealing. The Dash 201 designation follows AS568 standard sizing, allowing straightforward cross-referencing to OEM groove specifications in residential and commercial mechanical systems. The pack quantity of 25 supports both single repairs and scheduled maintenance stock.

Key Features

• Fluoroelastomer (Viton-type) material rated for continuous service up to 400 degrees F
• Dash 201 AS568 standard sizing: 0.188 inches ID, 0.438 inches OD, 0.125 inches thick
• 70 Shore A hardness with low compression set for sustained sealing force
• Good resistance to petroleum products, fuels, and oils
• Low gas permeability suitable for vacuum service applications
• Round cross section for compatibility with standard O-ring grooves

Compatibility

Designed as a standard Dash 201 AS568-sized O-ring for use in any groove machined to accept a 0.188-inch ID, 0.438-inch OD, 0.125-inch cross-section seal in petroleum-compatible fluid or gas systems.

Installation Notes

Power down or depressurize the system fully before replacing any O-ring seal. Inspect the groove for nicks, corrosion, or debris that could cause premature seal failure. Apply a compatible lubricant to ease installation and prevent twisting of the cross section during assembly. Follow applicable mechanical codes and the equipment manufacturer's torque and assembly specifications for the mating hardware.
