Value Collection ZMSCH70114 O-ring Dash 114 Nitrile Buna-n

Product Description

The VALUE COLLECTION ZMSCH70114 is a Dash 114 Buna-N (Nitrile Butadiene Rubber) O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and gas systems. It measures 0.625 inches inside diameter, 0.813 inches outside diameter, and 0.0937 inches thick. Rated at 70 Shore A hardness, this O-ring handles a working temperature range of -40 degrees F to 250 degrees F. It offers excellent resistance to petroleum-based fluids, strong compression set performance, and good tear and abrasion resistance. Licensed plumbers, HVAC technicians, and hydraulic system technicians commonly specify this size for valve, fitting, and pump sealing tasks.

The ZMSCH70114 is suited for residential and light commercial plumbing, HVAC refrigerant circuits, hydraulic lines, and pneumatic fittings where petroleum-compatible sealing is required. The Buna-N compound is the most widely used O-ring elastomer in the trade and is appropriate anywhere mineral oil, hydraulic fluid, fuel, or water-glycol contact is expected. This part ships in a package quantity of 100, making it practical for service vans stocking common seal sizes or for shop inventory replenishment.

Key Features

• Buna-N (Nitrile Butadiene Rubber) construction with excellent petroleum product resistance
• 70 Shore A hardness rating — classified as hard — for reliable compression sealing
• Operating range of -40 degrees F to 250 degrees F covers most HVAC, plumbing, and hydraulic service conditions
• Round cross section conforms to standard O-ring groove dimensions for Dash 114
• Meets SAE and MIL-Spec standards
• Package quantity of 100 units supports bulk stocking and service inventory needs

Compatibility

Compatible with petroleum products, mineral oils, hydraulic fluids, and water-glycol solutions. Designed as an OEM-style replacement O-ring for any application calling for a Dash 114 Buna-N seal. Note: Buna-N should not be used with ozone-generating environments, direct sunlight exposure, or incompatible synthetic fluids — verify media compatibility before installation.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Always depressurize and isolate the system before removing the old O-ring. Lightly lubricate the O-ring with a compatible grease or fluid before seating it to prevent twisting or nicking during assembly. Do not store unused O-rings near motors, electrical equipment, or direct sunlight, as ozone and UV exposure degrade Buna-N compound over time.
