Value Collection BDNA-9424 O-ring 44in Id 52in Od Nbr

Product Description

The VALUE COLLECTION BDNA-9424 is a large-diameter Nitrile Butadiene Rubber (NBR, also known as Buna-N) O-ring with a round cross section. It measures 44 inches inner diameter, 52 inches outer diameter, and 4 inches thick. NBR compound provides solid resistance to petroleum-based fluids, hydraulic oils, and fuels, making it a common choice in industrial sealing applications. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install seals of this type during equipment assembly or scheduled preventive maintenance on large-bore piping systems and machinery.

This O-ring is suited for large-bore static or low-dynamic sealing applications found in industrial plumbing, water treatment, pump housings, and fluid-handling systems. Its NBR material handles a broad range of petroleum-based and water-based media. The 4-inch cross-section thickness accommodates deep gland designs common in heavy industrial and municipal infrastructure equipment. A minimum order quantity of 10 units applies to this SKU.

Key Features

• 44 inches inner diameter and 52 inches outer diameter for large-bore gland fitment
• 4-inch cross-section thickness suits deep gland groove designs
• Nitrile Butadiene Rubber (Buna-N) compound resists petroleum-based fluids and hydraulic oils
• Round cross-section profile for standard O-ring groove seating
• Minimum order quantity of 10 units per order

Compatibility

Designed as an OEM-style replacement or maintenance seal for large-bore industrial fluid-handling equipment requiring a 44-inch ID, 52-inch OD, 4-inch thick NBR O-ring with a round cross section.

Installation Notes

Installation of large-diameter O-rings of this type is typically performed by licensed plumbers, pipefitters, or industrial maintenance technicians. Depressurize and drain the system fully before removing the old seal and seating the new ring. Inspect the gland groove for nicks, corrosion, or debris before installation, and apply a compatible fluid or lubricant to ease seating without damaging the elastomer. Follow applicable IPC or facility maintenance standards for large-bore sealing applications.
