Value Collection ZMSCH70MD215 O-ring Dash 215 Nbr 10-pack

Product Description

The VALUE COLLECTION ZMSCH70MD215 is a Dash 215 Buna-N (Nitrile Butadiene Rubber) O-ring with a round cross section, sold in a pack of 10. It measures 1.46 inches inside diameter, 1.312 inches outside diameter, and 0.125 inches thick, with a Shore A hardness of 70. Buna-N is the most widely used O-ring elastomer in industrial and trade applications, offering excellent resistance to petroleum-based fluids along with strong compression set, tear resistance, and abrasion resistance. Licensed technicians and journeyman tradespeople working with hydraulic, pneumatic, and fuel systems rely on this compound for dependable sealing performance across a broad temperature range.

This O-ring is suited for use in HVAC refrigerant lines, plumbing fittings, hydraulic systems, fuel systems, and general-purpose fluid sealing where contact with petroleum products is expected. Its rated temperature window of -40 degrees F to 250 degrees F makes it appropriate for both refrigeration applications and moderate-heat environments. The Dash 215 designation corresponds to a standard AS568 size, making it a straightforward replacement in any application specifying that dash number. Sold in a quantity of 10 per package, this SKU is practical for stocking service vehicles or parts bins.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or hydraulic system mechanics depending on the application. Always depressurize and isolate the system before removing or replacing any O-ring. Inspect the mating groove and sealing surface for scoring or corrosion before installing a new O-ring. Lightly lubricating the O-ring with a compatible fluid or grease helps prevent tearing during assembly and ensures even seating in the groove.
