Value Collection ZMSCV70039 Viton O-ring Dash 039

Product Description

The VALUE COLLECTION ZMSCV70039 is a Dash 039 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in fluid and gas systems. With a 2.75-inch inside diameter, a 2.875-inch outside diameter, and a 0.0625-inch cross-section thickness, this round-profile seal fits standard Dash 039 groove dimensions. Rated at 70 Shore A hardness, it handles a working temperature range of -15 degrees F to 400 degrees F, making it suitable for high-heat environments where standard nitrile or EPDM seals would degrade. HVAC technicians, plumbers, and industrial maintenance pros rely on fluoroelastomer seals where petroleum-based fluids, fuels, or elevated temperatures are present.

This O-ring is appropriate for use in residential and commercial HVAC equipment, refrigeration systems, hydraulic assemblies, fuel-handling lines, and plumbing connections exposed to petroleum products or high-temperature media. Its low gas permeability also makes it a reliable choice for vacuum service applications. The round cross-section seats consistently in standard O-ring grooves, minimizing installation variation. Sold in a package quantity of 10 units per order, making it practical to stock for service calls or repair kits.

Key Features

• Fluoroelastomer (Viton) compound offers wide chemical compatibility including petroleum products, fuels, and many industrial solvents
• Working temperature range of -15 degrees F to 400 degrees F suitable for high-heat HVAC and industrial applications
• Low compression set helps maintain a reliable seal over repeated thermal cycles
• Low gas permeability makes this seal appropriate for vacuum service
• 70 Shore A hardness rated Hard, resisting extrusion under moderate pressure
• Round cross-section profile fits standard Dash 039 O-ring grooves without modification

Compatibility

Designed as a standard Dash 039 replacement O-ring for any application requiring a 2.75-inch ID fluoroelastomer seal compatible with petroleum products, fuels, hydraulic fluids, and high-temperature media. Not FDA approved; not intended for food-contact or potable-water service.

Installation Notes

Installation should be performed by a qualified technician familiar with the system being serviced. Depressurize and isolate the fluid or gas circuit before removing the existing seal. Inspect the O-ring groove for nicks, scoring, or debris and clean the seating surface before installing the new seal. Avoid twisting or rolling the O-ring during installation; a light application of compatible lubricant helps seat the ring without damage.
