Value Collection ZMSCN70211 Neoprene O-ring Dash 211

Product Description

The VALUE COLLECTION ZMSCN70211 is a Dash 211 neoprene O-ring designed for static and dynamic sealing applications in refrigeration, HVAC, and general fluid systems. It features a round cross-section profile with an inside diameter of 0.796 inches, an outside diameter of 1.063 inches, and a thickness of 0.125 inches. Rated at 70 Shore A hardness, this O-ring handles a working temperature range of -65 degrees F to 250 degrees F. It resists petroleum products, ozone, and weathering, and is rated for use with refrigeration fluids including Freon. Sold in a package of 100 pieces, it suits shops and service fleets that keep standard sizes on hand.

This O-ring is suited for residential and light commercial HVAC and refrigeration equipment where neoprene seals are specified. Common applications include refrigerant line fittings, compressor service ports, and plumbing connections exposed to moderate petroleum-based fluids. The Dash 211 size is a widely used standard dimension in mechanical sealing systems. HVAC technicians and refrigeration mechanics typically stock neoprene O-rings in this size range for routine service and compressor changeouts. The 100-piece package quantity supports regular maintenance work and stocking requirements.

Installation Notes

Installation of O-rings in refrigeration and HVAC systems should be performed by a licensed HVAC technician or refrigeration mechanic following applicable EPA Section 608 handling requirements. Power down the system and recover refrigerant before opening any sealed circuit. Lubricate the O-ring lightly with a compatible refrigerant oil before seating to prevent damage during assembly. Do not over-stretch the O-ring during installation, as this can compromise the sealing surface.
