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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFDA-approved white NBR compound suitable for food-contact and sanitary applications\u003c\/li\u003e\n  \u003cli\u003e70-durometer hardness provides hard compression set resistance for reliable sealing under load\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to petroleum products, hydraulic oils, and related media\u003c\/li\u003e\n  \u003cli\u003eRound cross section with consistent 0.125-inch thickness for uniform groove seating\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F covers most HVAC and plumbing service conditions\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards; sold in packs of 10 with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 237 O-ring replacement compatible with petroleum products and systems requiring NBR elastomer seals.
