Value Collection ZMSCH70MD016 O-ring Dash 016 Nbr 25-pack

Product Description

The VALUE COLLECTION ZMSCH70MD016 is a Dash 016 nitrile butadiene rubber (NBR) O-ring with a 0.614 inch inside diameter, 0.75 inch outside diameter, and a 0.0625 inch thick round cross section. Hardness is rated at 70 Shore A, placing it in the hard category. NBR is the most widely used O-ring elastomer in trade applications, offering excellent resistance to petroleum-based fluids, strong compression set retention, and solid tear and abrasion resistance. Each package contains 25 pieces. This O-ring is installed by licensed plumbers, HVAC technicians, and mechanical contractors during system assembly, valve service, and fluid-line maintenance.

This O-ring is suited for static and dynamic sealing applications involving petroleum products, oils, fuels, and hydraulic fluids. The Dash 016 sizing is a standard dimension used across a wide range of valves, fittings, pumps, and mechanical assemblies in residential and light commercial HVAC, plumbing, and fluid-handling systems. The operating temperature range spans -40 degrees F to 250 degrees F, making it appropriate for both low-temperature and moderate-heat service environments. It is not FDA approved for food-contact use.

Key Features

• NBR construction delivers excellent resistance to petroleum products, oils, and hydraulic fluids
• 70 Shore A hardness rating provides reliable compression set and sealing force
• Rated for service from -40 degrees F to 250 degrees F
• Round cross section ensures consistent seating in standard O-ring grooves
• Dash 016 standard sizing fits a wide range of valves, pumps, and fittings
• Store away from direct sunlight, motors, and ozone-generating electrical equipment to preserve elastomer integrity

Compatibility

Designed for use with petroleum products and compatible fluid systems; suitable as a standard Dash 016 replacement O-ring in HVAC, plumbing, and mechanical fluid-handling assemblies where NBR elastomer is specified.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical contractors. De-energize all electrical systems and shut off fluid supply lines before disassembling any components. Lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent twisting or tearing during installation. Do not store unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade NBR elastomer over time.
