Value Collection ZMSCH70FDA237 O-ring Dash 237 Nbr 70 Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA237 is a Dash 237 O-ring manufactured from white nitrile butadiene rubber (NBR) with a 70-durometer hardness rating. It measures 3.359 inches inside diameter, 3.625 inches outside diameter, and 0.125 inches thick, with a round cross section. This O-ring carries FDA approval for use in food-contact applications and meets SAE and MIL-Spec standards. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this part as a sealing element in fluid and pneumatic systems where petroleum-based media resistance is required.

This O-ring is suited for residential and commercial sealing applications involving petroleum products, hydraulic fluids, and compatible media. It performs across a working temperature range of -40 degrees F to 250 degrees F, making it appropriate for a wide range of indoor and outdoor service conditions. The FDA-approved white NBR compound makes it a practical choice for food processing equipment, potable water-adjacent fittings, and sanitary systems that require both chemical resistance and compliance.

Key Features

• FDA-approved white NBR compound suitable for food-contact and sanitary applications
• 70-durometer hardness provides hard compression set resistance for reliable sealing under load
• Excellent resistance to petroleum products, hydraulic oils, and related media
• Round cross section with consistent 0.125-inch thickness for uniform groove seating
• Operating range of -40 degrees F to 250 degrees F covers most HVAC and plumbing service conditions
• Meets SAE and MIL-Spec standards; sold in packs of 10 with a minimum order quantity of 1

Compatibility

Designed as a standard Dash 237 O-ring replacement compatible with petroleum products and systems requiring NBR elastomer seals. Store away from direct sunlight, ozone sources, and electrical equipment that may generate ozone to preserve elastomer integrity.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics. De-pressurize and isolate the system completely before removing the old O-ring. Inspect the groove for debris, scoring, or corrosion before seating the new ring. Do not twist or overstretch the O-ring during installation, as deformation can compromise the seal.
