Value Collection ZMSCH70MD015 O-ring Dash 015 Nbr Pack of 25

Product Description

The VALUE COLLECTION ZMSCH70MD015 is a Dash 015 nitrile butadiene rubber (NBR) o-ring with a 0.563 inch inside diameter, 0.687 inch outside diameter, and a 0.0625 inch thick round cross section. Rated at 70 Shore A hardness, this o-ring is designed for static and dynamic sealing applications where petroleum product resistance is required. It operates across a temperature range of -40 degrees F to 250 degrees F. HVAC technicians, plumbers, and fluid system mechanics routinely use NBR o-rings of this size to seal fittings, valves, and fluid connections in refrigeration, hydraulic, and general-purpose pneumatic systems.

This o-ring is suited for residential and commercial trade applications wherever a Dash 015 standard-size seal is specified. Typical installation scenarios include refrigerant service port caps, hydraulic line fittings, pneumatic valve stems, and plumbing fixture connections. Its compatibility with petroleum-based fluids makes it a standard choice for fuel systems and oil-wetted assemblies. Sold in a package of 25, this SKU is appropriate for stocking service vehicles or supply rooms where multiple sealing jobs are anticipated.

• Round cross section geometry conforms to standard Dash 015 o-ring groove dimensions
• Black color; metal-detectable FDA-noted material (not FDA approved for food contact)
• Package quantity of 25 supports stocking for multi-unit service calls

Compatibility

Designed as a standard Dash 015 replacement o-ring compatible with petroleum-based fluid systems, hydraulic assemblies, pneumatic components, and general mechanical fittings that call for a 0.563 inch ID by 0.687 inch OD round-cross-section elastomeric seal.

Installation Notes

Installation of o-rings is typically performed by licensed HVAC technicians, plumbers, or mechanical technicians depending on the system type. Always depressurize and isolate the fluid circuit before removing any fitting or component that retains an o-ring. Lubricate the o-ring lightly with a compatible fluid or grease prior to seating to prevent tearing during assembly. Do not store unused o-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone degrades NBR elastomer.
