Is the 90° SAE 3000 / DIN 2353 Flange Connection, Carbon Steel, Type C3 rated for continuous operation at +100°C?

The 90° SAE 3000 / DIN 2353 Flange Connection, Carbon Steel, Type C3 is rated for continuous operation at +100°C. The product description specifies a temperature range from -20°C to +100°C, indicating it is designed to guarantee consistent functionality up to that maximum temperature under normal operating conditions.

Can the 90° SAE 3000 / DIN 2353 Flange Connection, Carbon Steel, Type C3 be used with alternative sealing materials for temperatures below -20°C?

90° SAE 3000 / DIN 2353 Flange Connection, Carbon Steel, Type C3 Format: The standard configuration is supplied with an NBR (nitrile) O‑ring and is specified for operation down to −20°C. NBR hardens and loses elasticity below its lower temperature limit, which increases leak risk. Using alternative sealing materials for temperatures below −20°C is possible, but requires choosing seals with suitable low‑temperature elastomeric properties (e.g., FKM/Viton has limited improvement, often similar or worse at very low temps; FFKM perfluoroelastomers offer better chemical resistance but still have cold‑temperature limits; silicone, EPDM, or specially formulated low‑temperature NBR grades can perform better). PTFE (Teflon) or molded metal‑backed seals are alternatives where elastomer flexibility is unacceptable, though they change sealing behavior and may require design/installation adjustments. Before substitution, verify: - Manufacturer approval or compatibility with the 90° SAE 3000 / DIN 2353 Flange Connection, Carbon Steel, Type C3 Format. - Temperature range and hardness (durometer) of the alternative seal at the lowest operating temperature. - Chemical compatibility with hydraulic fluid. - Fit, groove dimensions, and required preloads for reliable sealing. - Pressure and dynamic/static application (dynamic seals need elastomeric flexibility). Recommendation: Consult the flange/seal manufacturer for approved low‑temperature seal options or use engineered low‑temperature seals (e.g., specially compounded NBR or silicone/FFKM variants) tested and certified for your specific fluid, pressure and temperature conditions prior to field use.
