The VALUE COLLECTION ZMSCS70FDA236 is a Dash 236 silicone O-ring with a round cross section, designed for static and dynamic sealing applications that demand a wide service temperature range and reliable chemical resistance. With a 3.234-inch inside diameter, 3.5-inch outside diameter, and 0.125-inch thickness, this ring meets FDA-compliant material standards. Hardness is rated at 70 Shore A, placing it in the hard rating category. It is well suited for systems handling oils, chemicals, and solvents where consistent sealing performance between -80 degrees F and 450 degrees F is required. Sold in packages of 10.
This O-ring is used in plumbing, HVAC, food processing, pharmaceutical, and general industrial equipment where FDA-compliant sealing materials are specified. The silicone compound provides good dry heat resistance and strong resistance to weathering and ozone degradation. It is appropriate for both residential and commercial applications where temperature extremes or sanitary requirements make standard Buna-N or EPDM compounds unsuitable. Technicians and maintenance professionals install these during pump rebuilds, valve overhauls, manifold servicing, and equipment assembly.
Designed as a standard Dash 236 O-ring replacement for any groove or gland machined to the Dash 236 cross-section standard, across plumbing, HVAC, food processing, and general industrial sealing applications.
Licensed plumbers, HVAC technicians, and mechanical maintenance professionals typically install O-rings of this type. Always depressurize and de-energize the system before disassembly and remove all fluid from the sealing area. Inspect the mating groove for burrs, corrosion, or damage before seating the new ring. Do not twist or stretch the O-ring during installation, and apply a compatible lubricant to ease seating and prevent tearing on assembly.
