Value Collection ZMSCH70FDA236 O-ring Dash 236 Nbr Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA236 is a Dash 236 O-ring manufactured from white nitrile butadiene rubber (NBR/Buna-N) and rated FDA-approved for food-contact applications. It features a round cross section with a 3.234-inch inside diameter, 3.5-inch outside diameter, and 0.125-inch thickness. Hardness is rated at 70 Shore A, placing it in the hard range for reliable compression set performance. NBR is the most widely used O-ring elastomer in trade applications, offering strong resistance to petroleum-based fluids, good tear strength, and abrasion resistance. Licensed plumbers, pipefitters, and maintenance technicians install this type of seal in fluid-handling assemblies across HVAC, plumbing, and industrial systems.

This O-ring is suited for static and dynamic sealing applications where contact with petroleum products, oils, fuels, or hydraulic fluids is expected. The FDA-approved white Buna-N compound makes it appropriate for use in food-processing equipment, potable water systems, and sanitary fluid lines where material compliance is required. It carries SAE and MIL-Spec standards compliance. Operating temperature range spans -40 degrees F to 250 degrees F, supporting a broad range of residential and light commercial service environments. Sold in a package quantity of 10 with a minimum order quantity of 1.

Installation Notes

Licensed plumbers, pipefitters, or qualified maintenance technicians should install this seal. Depressurize and drain the system fully before disassembling any fitting or valve housing. Inspect the mating groove for burrs, nicks, or contamination before seating the O-ring. Avoid rolling or twisting the ring during installation to prevent stress-induced leaks in service.
