Value Collection ZMSCH90334 O-ring Dash 334 Nitrile

Product Description

The VALUE COLLECTION ZMSCH90334 is a Dash 334 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in fluid sealing applications. It measures 2.625 inches inside diameter, 3 inches outside diameter, and 0.1875 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring handles a temperature range of -40 degrees F to 250 degrees F. It is sold in a package of 25 units. Plumbers, hydraulic technicians, and HVAC mechanics install this type of seal in fittings, valves, and fluid system connections where petroleum-based media resistance is required.

This O-ring is suited for residential and commercial applications involving petroleum products, hydraulic fluids, and general-purpose fluid sealing. The Buna-N compound delivers reliable compression set resistance and strong tear and abrasion resistance under sustained dynamic or static loading. It conforms to SAE and MIL-Spec standards, making it appropriate for industrial, mechanical, and HVAC service work. The 25-piece package quantity supports service shops and field technicians who replace O-rings in volume during preventive maintenance or equipment rebuilds.

Key Features

• Buna-N (Nitrile Butadiene Rubber) compound offers excellent resistance to petroleum products and hydraulic fluids
• 90 durometer extra-hard rating provides high resistance to extrusion under pressure
• Wide temperature range: -40 degrees F to 250 degrees F
• Round cross section at 0.1875 inches thickness suits standard Dash 334 groove dimensions
• Meets SAE and MIL-Spec standards
• Package of 25 units supports high-volume service and maintenance work

Compatibility

Designed as a standard Dash 334 O-ring replacement for use with petroleum products and compatible fluids in valves, fittings, pumps, and fluid system components requiring a 2.625-inch ID seal.

Installation Notes

Depressurize and drain the fluid system completely before removing or installing O-rings. Inspect the mating groove for burrs, scoring, or contamination that could damage the new seal. Apply a thin film of compatible lubricant to the O-ring before installation to reduce the risk of tearing during assembly. Store unused O-rings away from direct sunlight, ozone sources, and electrical equipment to prevent premature degradation of the elastomer.
