Value Collection QH70K Nbr O-ring Kit 70 Shore a 226 Piece

Product Description

The VALUE COLLECTION QH70K is a nitrile butadiene rubber (NBR) O-ring kit designed for sealing applications across plumbing, HVAC, and fluid-handling systems. The kit contains 226 individual O-rings, each featuring a Quattro cross-section (X-profile) geometry rather than a standard round cross section. This X-profile increases the sealing contact area and reduces the tendency for the ring to roll or twist during installation. The compound is rated at 70 Shore A durometer, placing it in the hard range for NBR elastomers. NBR is well suited for use with petroleum-based oils, fuels, water, and many hydraulic fluids.

This kit is appropriate for residential and commercial service work where technicians need a variety of O-ring sizes on hand for repairs to valves, fittings, pumps, and fluid-control components. The X-profile design makes it a useful option for grooved-gland applications where standard round O-rings may displace under pressure. Plumbers, HVAC technicians, and equipment service professionals typically keep assortment kits like this for field repairs and preventive maintenance work. All 226 pieces are included in a single package, minimizing restocking frequency on the service truck or shop bench.

Key Features

• Quattro X-profile cross section resists rolling and twisting in the gland during installation
• Nitrile butadiene rubber compound provides good resistance to petroleum oils, hydraulic fluids, and water
• 70 Shore A durometer rating for a hard, resilient seal under compression
• 226-piece kit supports a wide range of repair and maintenance tasks from a single package
• Minimum order quantity of 1 package for straightforward procurement

Compatibility

Designed as an OEM-style replacement and general-service O-ring kit for use in valves, pumps, fittings, and fluid-handling components that accept X-profile NBR seals rated at 70 Shore A durometer.

Installation Notes

O-ring installation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanical service professionals. Before replacing any O-ring, shut off and depressurize the system completely and follow applicable IPC or IFGC requirements for the service type. Inspect the gland groove for scoring or corrosion before seating the new ring, and apply a compatible lubricant to ease installation without damaging the elastomer. Do not overstretch the O-ring during placement, as this reduces its effective cross-section and compromises the seal.
