How We Match Your Rubber Gasket Requirements?
Whether you’re replacing a worn factory gasket or specifying a new design, we start by matching your requirements — dimensions from a drawing, standard flange specs (ASME, DIN, JIS), or a physical sample you send us for exact replication. We help you select the right hardness and material for your media and operating conditions, including FDA-grade, RoHS-compliant, and chemical-resistant options where required. Red and black compounds are available for on-site color coding by material or pressure rating. From prototype to production runs, we hold tight tolerances and consistent thickness batch to batch — so replacement gaskets fit exactly like the original, every time.

It depends on the environment—NBR is best for oil, EPDM for outdoor/weather, and FKM for chemicals or high heat.
Typically 20–30% compression is ideal for effective sealing without over-stressing the gasket.
In most cases, no. Once compressed or chemically aged, gaskets lose effectiveness and should be replaced.
Yes, we offer FDA-approved silicone and EPDM gaskets suitable for food, beverage, or medical applications.
Absolutely. We support custom cutting and molding for oversized or complex gasket geometries.
