Value Collection ZMSCV70109 Viton O-ring Dash 109 Pack 50

Product Description

The VALUE COLLECTION ZMSCV70109 is a Dash 109 Viton (fluoroelastomer) O-ring used to create a reliable fluid or gas seal in hydraulic, pneumatic, and fluid-handling assemblies. It has a 0.313-inch inside diameter, a 0.500-inch outside diameter, and a 3/32-inch (0.0937-inch) cross-section thickness. The round cross-section profile seats cleanly into standard Dash 109 grooves. With a Shore A hardness of 70 and a working temperature range of -15 degrees F to 400 degrees F, this O-ring is well suited for high-temperature and chemical-resistant sealing applications. It is installed by licensed plumbers, pipefitters, HVAC technicians, and hydraulic system mechanics.

This O-ring is designed for use in systems that handle petroleum products, fuels, oils, and a wide spectrum of industrial chemicals. Its fluoroelastomer compound provides low compression set, high temperature resistance, and low gas permeability, making it appropriate for vacuum service as well as pressurized fluid circuits. Typical applications include valve stems, pump shafts, hydraulic fittings, refrigerant service ports, and fuel system connections. Each order unit contains 50 O-rings, making it practical for service shops and fleet maintenance operations that replace seals routinely.

Key Features

• Fluoroelastomer (Viton) construction provides strong resistance to petroleum products, oils, and fuels
• Working temperature range of -15 degrees F to 400 degrees F suits high-heat environments
• Low compression set maintains long-term sealing force under sustained load
• Low gas permeability and good vacuum service performance
• Round cross-section profile fits standard Dash 109 O-ring grooves
• Pack of 50 units supports shop stocking and bulk seal replacement work

Compatibility

Designed as a direct replacement for any application requiring a standard Dash 109 O-ring with a 0.313-inch ID, 0.500-inch OD, and 3/32-inch cross-section thickness in fluoroelastomer material. Compatible with petroleum products, oils, fuels, and a wide spectrum of industrial chemicals per the manufacturer specification. Note: this O-ring is not FDA approved and should not be used in food-contact or potable-water applications.

Installation Notes

Power down or depressurize the system completely before removing the old O-ring and installing a replacement. Lubricate the O-ring with a compatible fluid or assembly lubricant before seating it to prevent rolling or tearing during installation. Do not use petroleum-based lubricants on O-ring materials that are not rated for petroleum compatibility. Follow applicable plumbing, hydraulic, or HVAC service codes and the equipment manufacturer's groove tolerance specifications when selecting and installing O-rings.
