Value Collection ZMSCH70029 O-ring 1.5 in Id Nbr Dash 029

Product Description

The VALUE COLLECTION ZMSCH70029 is a Dash 029 O-ring made from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in sealing applications. It measures 1.5 inches inside diameter, 1.625 inches outside diameter, and 0.0625 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set performance along with strong tear and abrasion resistance. It is well suited for systems that contact petroleum-based fluids. Plumbers, HVAC technicians, and hydraulic service professionals install these in a wide range of fluid-handling and sealing applications.

This O-ring is used in residential and commercial plumbing, HVAC refrigerant circuits, hydraulic systems, and general industrial fluid connections where petroleum product exposure is expected. The Buna-N compound performs across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for most standard mechanical and fluid sealing scenarios encountered in trade service work. It conforms to SAE and MIL-Spec standards. Sold in a package of 100 pieces, it is practical for service shops and contractors who need a reliable stock of this size on hand.

Compatibility

Designed as a standard Dash 029 replacement O-ring suitable for petroleum-compatible sealing applications in plumbing, HVAC, hydraulic, and general industrial systems. Not recommended for use with ozone-generating equipment or in direct sunlight storage conditions.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or hydraulic service professionals depending on the application. Always depressurize and drain the system before replacing an O-ring, and shut off any relevant fluid supply lines. Lubricate the O-ring with a compatible lubricant before seating to prevent rolling or pinching during assembly. Do not store unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N material over time.
