Value Collection BDNA-9995 O-ring Dash 204 Nbr 3/8 in Id

Product Description

The Value Collection BDNA-9995 is a Dash 204 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 3/8 inch inside diameter and 1/8 inch thickness, making it a standard inch-system seal used across a wide range of fluid and gas containment applications. NBR offers solid resistance to petroleum-based oils, fuels, and hydraulic fluids, which makes this O-ring a practical choice for plumbing, HVAC, and general mechanical assemblies. Installation is straightforward and requires no special tooling beyond proper groove preparation and light lubrication of the seal prior to seating.

This O-ring is suited for use in residential and light commercial applications wherever a Dash 204 inch-series seal is specified. Typical install scenarios include valve bodies, fitting connections, pump housings, and refrigeration service ports where NBR material compatibility with the working fluid has been confirmed. It is installed by plumbers, HVAC technicians, and general maintenance mechanics. The part ships individually but carries a minimum order quantity of 25 units, which aligns with standard service-stock purchasing.

Key Features

• Dash 204 standard sizing: 3/8 inch inside diameter, 1/8 inch thickness
• Nitrile Butadiene Rubber (NBR) construction resists petroleum-based oils, fuels, and hydraulic fluids
• Round cross section for consistent groove seating and even compression
• Inch-system dimensioning for direct compatibility with standard inch-series hardware
• Lightweight at 0.01 pounds for easy handling and bulk stocking

Compatibility

Designed as an OEM-style replacement or service seal for any application specifying a Dash 204 inch-series NBR O-ring with a 3/8 inch inside diameter and 1/8 inch round cross section thickness.

Installation Notes

Depressurize and drain the system before removing the old O-ring to prevent fluid release or injury. Clean the groove thoroughly and inspect for damage or corrosion before installing the new seal. Apply a light coat of compatible lubricant to the O-ring prior to installation to reduce the risk of tearing during assembly. Confirm NBR material compatibility with the working fluid or refrigerant before placing the seal in service.
