What We Manufacture

Silicone sponge takes -60°C to +200°C without complaint. It seals under the lightest closure force, so thin lids and lightweight doors actually close instead of warping against a solid profile. And it barely ages. Sun, ozone and heat cycling do very little to it.

An extruded silicone gasket can land cheaper than a moulded EPDM one. A moulded gasket needs a mould, and you pay for it. An extrusion die costs a fraction of that and is cut in days. Join the extrusion into an endless loop and any perimeter is possible, still with no mould to pay for. Most buyers assume the opposite until they see the quote.

Silicone (VMQ), EPDM, FKM (Viton), NBR, Neoprene (CR) and SBR, plus over 1000 custom formulations developed in-house for specific temperature, chemical and IP requirements. Tell us your operating conditions and we'll recommend the right compound.

Yes, both, and on a dedicated continuous vulcanizing line of their own. Moulded EPDM gaskets, washers, O-rings and grommets to your drawing, and extruded EPDM profiles, channels, sponge sections and joined endless loops down to 40 Shore A. EPDM is the cost-effective choice wherever a seal sits outdoors: UV, ozone and weathering resistance close to silicone, at a lower price, provided there is no oil or fuel contact and the temperature stays inside −50°C to +110°C.

Yes. Our grommets have passed IP66, IP67 and IP68 testing as part of our customers' products, and our gaskets and seals go into IP-rated products such as luminaires and enclosures.

From prototypes to millions of pieces. We turn samples around extremely quickly, and repeat orders on existing tooling ship fast.

Yes. Silton has supplied the Indian and United States markets since 2002, backed by a four-decade OEM track record. Send a drawing and we will quote.

Yes. Send a sample, drawing, or datasheet. We reverse-engineer it and make it here, often for less than it costs to import.

A profile extruded to precise length with the cut ends joined into an endless loop, with no new tooling for a different perimeter. Silicone joints are vulcanised silicone to silicone, with no glue. EPDM is vulcanised in thick sections and bonded with cyanoacrylate in thin ones. A vulcanised joint compresses like the rest of the profile, so the IP rating holds around the full loop.

30 Shore A, very soft, requiring specialised compounding and die design. Ideal where low closure force is critical: LED luminaires, electronics enclosures, medical housings. Sponge and foam profiles go softer still.

Yes. We extrude silicone tubing in compliant grades for food contact, pharmaceutical, and potable water applications, formulated to FDA 21 CFR 177.2600, BfR Recommendation XV, USP Class VI (chapters 87 and 88) biological reactivity requirements, and BS 6920 (WRAS) for drinking water contact. Sizes from 1 mm to 40 mm ID, custom wall thicknesses to your drawing. Tell us your application and the compliance documentation your industry requires, and we will confirm the right grade before you order.

Absolutely. Send a drawing in any format: STEP, IGES, Parasolid, DXF, PDF, even a hand sketch. We've made everything from micro O-rings under 5 mm to panel seals over a metre long.

Our grommets have passed IP66, IP67 and IP68 testing as part of our customers' products, and our gaskets and seals go into IP-rated products such as luminaires. An IP rating belongs to the finished product, so tell us your enclosure and duty and we will suggest the right section and compound.
