***Please note: At Seal House, we have seen this seal in pumps where OEM manual states U109-220 or U90451SS (this is 3883 in viton material). Our standard replacement is 3883, for non chemical applications and temperatures below 220°F . For chemical service or temperatures above 220°F, you need 3883 with viton material, which is equivalent to OEM U90451SS. Please contact us for viton pricing and delivery
