The VALUE COLLECTION ZMSCH90151 is a Dash 151 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber), one of the most widely used elastomers in industrial and trade sealing applications. It measures 3 inches inside diameter, 3.188 inches outside diameter, and 0.093 inches thick with a round cross section. The compound is rated at 90 durometer, placing it in the extra-hard hardness category, and it carries a working temperature range of -40 to 250 degrees F. Sold in a package quantity of 50, this O-ring is a standard choice for plumbers, pipefitters, HVAC technicians, and maintenance professionals who need reliable static or dynamic seals in petroleum-based fluid systems.
This O-ring is suited for use in hydraulic systems, pneumatic assemblies, fuel handling equipment, and general industrial plumbing applications where contact with petroleum products is expected. The Buna-N compound offers excellent resistance to petroleum-based fluids, along with strong compression set resistance and good tear and abrasion resistance. It conforms to SAE and MIL-Spec standards, making it appropriate for both commercial maintenance and specification-driven projects. The Dash 151 designation is a standard AS568 size reference used across a wide range of OEM and aftermarket sealing applications.
Designed as a standard Dash 151 O-ring replacement compatible with petroleum-product-based systems including hydraulic, pneumatic, and fuel handling assemblies. Compatible with petroleum products; not recommended for exposure to ozone, direct sunlight, or electrical equipment generating ozone.
Installation should be performed by a licensed plumber, pipefitter, or qualified maintenance technician following applicable IPC or system-specific sealing procedures. Shut off and depressurize the system completely before removing or installing any O-ring. Avoid stretching the O-ring over sharp edges during installation; use an appropriate O-ring lubricant compatible with Buna-N and the system fluid. Do not store unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as this will degrade the elastomer.
