Value Collection ZMSCN70117 Neoprene O-ring Dash 117

Product Description

The VALUE COLLECTION ZMSCN70117 is a Dash 117 neoprene O-ring designed for sealing applications in refrigeration, HVAC, and fluid-handling systems. It has an inside diameter of 0.799 inches, an outside diameter of 1.000 inch, and a cross-section thickness of 0.0937 inches (3/32 inches). The round cross-section profile seats reliably in standard dash-117 grooves. With a hardness rating of 70 Shore A, this O-ring provides a firm compression set suitable for static and dynamic sealing. Neoprene construction gives it moderate resistance to petroleum products along with good ozone and weather resistance, making it a practical choice for refrigerant-side seals handled by HVAC and refrigeration technicians. Sold in a package of 100.

This O-ring is suited for residential and light commercial HVAC and refrigeration equipment where Freon-compatible seals are required. Typical applications include compressor service ports, refrigerant line fittings, condensate and fluid-handling connections, and similar dash-117 groove locations. The neoprene compound performs across a wide service temperature range, from -65 degrees F to 250 degrees F, covering most refrigeration and air-conditioning operating conditions. Plumbing and refrigeration technicians also use this size in water and low-pressure fluid fittings where neoprene compatibility is acceptable.

Key Features

• Neoprene compound rated compatible with Freon refrigerants
• Moderately resistant to petroleum products
• Good ozone and weather resistance for longevity in exposed installations
• Operating temperature range: -65 degrees F to 250 degrees F
• 70 Shore A hardness for reliable compression set in standard grooves

Compatibility

Designed as an OEM-style replacement seal for any application requiring a Dash 117 O-ring in a neoprene-compatible, Freon-rated compound. The neoprene material is not FDA approved and should not be used in food-contact or potable-water applications without verification of local code requirements.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic following applicable EPA Section 608 and equipment manufacturer guidelines. Recover and isolate refrigerant before opening any sealed system. Lubricate the O-ring lightly with a compatible refrigerant oil before seating to prevent rolling or tearing during assembly. Do not reuse O-rings removed from pressurized joints.
