Langfang Xinhong Sealing Materials Co., Ltd.

EPDM flange gasket with full-face and bolt-hole form.
Xinhong’s own product selection names a full-face EPDM gasket with drilled bolt holes. The catalog establishes the material family and gasket form, but does not determine the correct fit for every flange. Buyers should supply the flange drawing, gasket thickness and service medium so the supplier can confirm the actual compound and finished dimensions.
