Value Collection ZBD9994-X O-ring Dash 330 Nbr 2.13 in Id

Product Description

The VALUE COLLECTION ZBD9994-X is a Dash 330 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 2.13 inches inside diameter, 2.50 inches outside diameter, and 0.1875 inches (3/16 inches) thick. NBR construction provides reliable resistance to petroleum-based fluids, hydraulic oils, and fuels, making this O-ring a standard sealing choice across plumbing, HVAC, and mechanical fluid systems. Shore hardness is rated at 70, placing it in the hard durometer range for firm seating under pressure. Licensed plumbers, HVAC technicians, and maintenance mechanics commonly install this part as a static or low-motion dynamic seal.

This O-ring is suited for use in residential and light commercial applications where a Dash 330 standard size is specified. Typical use cases include pipe unions, valve bodies, pump housings, and hydraulic fittings where a dependable NBR seal is required. The rated temperature range of -40 degrees F to 275 degrees F covers most standard HVAC and plumbing operating conditions. This part is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance mechanics. Shut off fluid supply and relieve system pressure completely before removing the old O-ring or installing the replacement. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant prior to seating to prevent tearing during assembly. Inspect the groove for nicks, corrosion, or debris before installation to ensure a proper seal.
