Value Collection ZMSCN70212 Neoprene O-ring Dash 212 100pk

Product Description

The VALUE COLLECTION ZMSCN70212 is a Dash 212 neoprene O-ring designed for static and dynamic sealing applications across HVAC, refrigeration, and plumbing systems. The ring measures 0.875 inches inside diameter, 1.125 inches outside diameter, and 0.125 inches thick, with a round cross section and a Shore A hardness of 70. Neoprene construction provides moderate resistance to petroleum-based products, good ozone and weather resistance, and reliable compression set performance. This item is sold in a package quantity of 100 rings, making it well suited for service fleets and shop stock replenishment.

This O-ring is commonly used in refrigeration and air conditioning systems where Freon-compatible sealing material is required. The neoprene compound performs across a wide temperature range, from -65 degrees F to 250 degrees F, covering most residential and light commercial HVAC and refrigeration service conditions. HVAC technicians and plumbers install this ring in valve bodies, flare fittings, and refrigerant-side connections where ozone and weather exposure are a concern. The Dash 212 designation makes cross-referencing straightforward when matching to OEM seal kits.

Compatibility

Designed as an OEM-style replacement or service-stock O-ring for any application calling for a Dash 212 round-cross-section neoprene seal, including refrigerant-side fittings, valve bodies, and plumbing connections compatible with neoprene elastomers.

Installation Notes

HVAC technicians and plumbers should recover or isolate refrigerant or fluid pressure from the system before disturbing any sealed connection. Inspect the seating groove for nicks, corrosion, or debris before installing the new ring. Lightly lubricate the O-ring with a compatible refrigeration oil or assembly lubricant to aid installation and prevent rolling in the groove. Follow applicable service codes and manufacturer torque guidance when reassembling fittings.
