The fill fluid is silicone oil DC200 at 10 cSt, which keeps thermal response stable across the typical instrument range and avoids the viscosity shift of heavier oils in cold starts. The diaphragm is AISI 316L stainless steel, giving it the pitting resistance needed for chloride-bearing media or washdown environments. The mounting flange is ASME CL 900-1500 in a 2-inch size, so it mates directly to the corresponding process nozzle without an adapter ring. Capillary length is 3 meters (10 feet), protected by an AISI 316L stainless steel armour that prevents kinking and mechanical damage during installation or vibration. The high-pressure side connection (H) means the seal mounts on the HP port of the transmitter, which is the standard arrangement for differential pressure applications. ## Configuration notes The flushing ring option is specified as 'none' (N), so there is no flushing connection on this seal — if the process fluid tends to clog or crystallize at the diaphragm face, a version with a flushing ring would be the better call. The seal surface finish is serrated (1), which improves the grip on the mating gasket and reduces the chance of leakage at high flange pressures. The mounting flange material is AISI 316 stainless steel, matching the diaphragm material for corrosion consistency across the wetted assembly.","metaTitle":"S26RAHE5SFSM1AESNNN Rotating Flange Diaphragm Seal, ASME CL","metaDescription":"S26RAHE5SFSM1AESNNN rotating flange diaphragm seal (flush/extended) with silicone oil fill, AISI 316L SS diaphragm, ASME CL 900-1500 / 2 in. flange.
