Value Collection ZMSCH90006 O-ring Dash 006 Buna-n 90D

Product Description

The VALUE COLLECTION ZMSCH90006 is a Dash 006 Buna-N (Nitrile Butadiene Rubber) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and fluid-handling systems. It measures 0.125 inches inside diameter, 0.25 inches outside diameter, and 0.0625 inches in cross-section thickness. Rated at 90 durometer (extra hard), this O-ring delivers strong compression set resistance, excellent tear and abrasion resistance, and reliable sealing performance with petroleum-based fluids. Licensed tradespeople specify Buna-N as the standard elastomer for most oil and refrigerant-adjacent sealing tasks. Sold in packages of 100 units with a minimum order quantity of 1 package.

This O-ring is well suited to residential and light commercial HVAC equipment, refrigeration fittings, plumbing valves, and hydraulic or pneumatic assemblies where petroleum product exposure is expected. The Dash 006 designation follows SAE and MIL-Spec standard sizing, making it a straightforward drop-in for any application calling out a 006-series O-ring. Its operating temperature range of -40 to 250 degrees F covers the majority of mechanical sealing environments encountered in field service.

Key Features

• Buna-N (NBR) elastomer — the most widely used O-ring material for petroleum product compatibility
• 90 durometer extra-hard rating provides superior compression set and extrusion resistance
• Temperature range: -40 to 250 degrees F for broad field applicability
• SAE and MIL-Spec compliant Dash 006 standard sizing
• Round cross-section profile for consistent groove seating and reliable face or radial seals
• Packaged in quantities of 100 — practical for bench stock and service van inventory

Compatibility

Compatible with petroleum products and oils. Designed as an OEM-style replacement or service-stock O-ring for any Dash 006 groove specification conforming to SAE or MIL-Spec standards. Not recommended for use with ozone, direct sunlight exposure, or equipment generating ozone such as electric motors without protective shielding.

Installation Notes

Installation is performed by HVAC technicians, plumbers, and hydraulic system mechanics as part of valve, fitting, or component service. Always depressurize and isolate the system before removing or replacing seals. Lightly lubricate the O-ring with a compatible lubricant prior to installation to prevent tearing during assembly. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as this will degrade the elastomer over time.
