Value Collection ZMSCH90029 O-ring 1.5 in Id Nbr Dash 029

Product Description

The VALUE COLLECTION ZMSCH90029 is a Dash 029 nitrile butadiene rubber (Buna-N) O-ring rated for a wide temperature range of -40 to 250 degrees F. It measures 1.5 inches inside diameter, 1.625 inches outside diameter, and 0.0625 inches (1/16 inch) thick with a round cross section. The durometer hardness is 90, placing it in the extra-hard category. This O-ring is one of the most widely used elastomer seals in the trade, installed by plumbers, HVAC technicians, and fluid-system mechanics wherever a reliable static or dynamic seal against petroleum-based media is required.

This O-ring is suited for sealing applications in hydraulic, pneumatic, and fuel-handling systems that involve petroleum products. The Buna-N compound delivers excellent compression set resistance along with strong tear and abrasion resistance, making it appropriate for both static groove seals and low-speed dynamic applications in residential and light commercial equipment. Each package contains 100 pieces, which is practical for shop stock or service van inventory where multiple repairs are anticipated.

Compatibility

Compatible with petroleum products and petroleum-based hydraulic fluids. Designed as a standard Dash 029 O-ring replacement for any groove dimensioned to accept a 1.5-inch ID by 1.625-inch OD by 1/16-inch cross-section seal. Not FDA approved; not recommended for food-contact or ozone-heavy environments.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics following relevant system-specific codes. Always depressurize and de-energize the system before removing the old seal and seating the replacement. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before installation to prevent twisting or nicking during assembly. Do not store unused O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone exposure degrades nitrile rubber.
