Value Collection ZMSCV70149 Viton O-ring Dash 149

Product Description

The VALUE COLLECTION ZMSCV70149 is a Dash 149 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in fluid and gas systems. It features a round cross section with a 2.813-inch inside diameter, 3-inch outside diameter, and a wall thickness of 0.094 inches. Rated at 70 Shore A hardness, this O-ring is suited for sealing environments involving petroleum-based fluids, hydraulic media, and high-temperature service. It is sold in a package of 10 and is commonly installed by licensed plumbers, HVAC technicians, and industrial maintenance professionals working on fluid-handling and pneumatic systems.

This O-ring is appropriate for use in applications requiring good resistance to petroleum products, low compression set, and high-temperature tolerance. It is rated for service from -15 degrees F to 400 degrees F, making it a reliable choice for demanding thermal environments. The low gas permeability characteristic makes it suitable for vacuum service as well. Typical installation scenarios include pump seals, valve stems, hydraulic fittings, and similar mechanical connections in both residential and commercial systems.

Key Features

• Fluoroelastomer (Viton) material provides wide chemical compatibility and high-temperature resistance
• Rated from -15 degrees F to 400 degrees F operating temperature range
• 70 Shore A hardness for reliable sealing under compression
• Round cross section with 0.094-inch wall thickness for standard Dash 149 groove fitment
• Low gas permeability makes it appropriate for vacuum service applications
• Good resistance to petroleum products with low compression set

Compatibility

Designed as a standard Dash 149 O-ring replacement for applications involving petroleum products, hydraulic fluids, and high-temperature sealing environments where fluoroelastomer material is specified.

Installation Notes

Installation should be performed by a qualified technician familiar with the equipment being serviced. Depressurize and de-energize the system completely before removing existing seals or disassembling fittings. Inspect the groove for damage or debris before seating the O-ring, and avoid twisting or overstretching during installation. Use a compatible lubricant approved for fluoroelastomer compounds when inserting into the groove.
