Value Collection ZMSCH70MD017 O-ring Dash 017 Nbr Pack of 25

Product Description

The VALUE COLLECTION ZMSCH70MD017 is a Dash 017 O-ring made from Nitrile Butadiene Rubber (NBR), the most widely used elastomer for sealing applications in HVAC, plumbing, and fluid-system work. It measures 0.676 inches inside diameter, 0.812 inches outside diameter, and 0.0625 inches thick (1/16 inches), with a round cross section and a Shore A hardness of 70. Rated for service from -40 degrees F to 250 degrees F, this O-ring delivers excellent resistance to petroleum-based fluids along with strong compression set, tear resistance, and abrasion resistance. Licensed trades and general maintenance technicians install these in high-volume quantities where a reliable, catalog-standard NBR ring is required.

This O-ring is suited for residential and commercial applications involving petroleum-based fluids, hydraulic oil, fuel systems, refrigeration service valves, and general plumbing connections. Its Dash 017 sizing is a catalog-standard dimension, making it a direct fit in any gland designed to that specification. Each package contains 25 rings, supporting service kits, bulk restocking, or multi-unit jobs where multiple sealing points need to be addressed in a single call. NBR is not recommended for use with ozone-generating environments or direct sunlight exposure during storage.

Compatibility

Designed to fit any standard Dash 017 O-ring gland per catalog dimensions, commonly used in HVAC service valves, plumbing fittings, and hydraulic or petroleum fluid system components compatible with NBR elastomers.

Installation Notes

Installation should be performed by a qualified technician following applicable codes such as the IPC or IFGC depending on the system type. Always depressurize and isolate the system before removing or replacing O-rings. Lubricate the O-ring with a compatible fluid or grease prior to seating to prevent tearing during installation. Do not store unused rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade NBR over time.
