We can supply sponge in extruded profile sections (including tube, flat strip, irregular shapes & round cord) as well as sheet. We are also able to join our sponge products to form endless seals & gaskets. Please contact us with your requirements.

Joined / Formed Gaskets

Joined / Formed Gaskets – ISG can supply a large selection of custom made joined seals & gaskets upon request. Using a very strong vulcanization process our gaskets can retain the same compression & hardness unlike ‘glue’ which often hardens or turns brittle & delaminates (breaks) over time.
We supply simple custom size O’rings (square or round profile) to very complicated profiled sections which could require right angle joins or simple ‘butt’ joins.
We can also graphite coat some gaskets for ’non-stick’ applications such as Auto Clave seals.
Please contact us with your requirements or designs for expert advice or quotation.

Pinchweld Extrusions

Pinchweld Extrusions are also available from ISG. Made from durable EPDM with a steel insert, these are a great & economic way to add a seal to enclosures which have a finished edge for the seal to push onto. Please see under our ‘Drawings’ page for profile selection.


Fiberglass Vacuum Bagging Seals The range of RTM Silicone Seal Extrusions are available from ISG for your Fiberglass Vacuum Bagging needs. Vacuum bagging is a commonly used technique in composites, and for good reason. When done correctly, your part will have a nice, uniformly distributed compression about the surface of the layup. This in turn helps to minimize any voids (e.g. bubbles and wrinkles) in the buildup of layers. Also, when used with a porous substrate made of peel-ply and breather-cloth it assists in having the optimal ratio of resin to reinforcement (e.g fiberglass, or carbon fiber, or Kevlar) by squeezing out the excess. Please see our ‘drawings’ page for profile details or email for further information.

Compression Packing

Industrial Seals & Gaskets supply a wide variety of compression packings for most applications including Carbon, Fiberglass Braid, Expanded PTFE & Gaphite ect For specific information, please contact us at for further assistance.


Poly Belting Cord

Industrial Seals & Gaskets are able to supply a range of Solid Round PU Belting (Poly Cord). ‘Food Quality’ belting which are used in Food Processing applications, conveying products such as Sliced Meats, Confectionery, Cheese & Fish ect are often supplied in Blue PU or Blue Metal Detectable PU. These are Food Grade & have properties which restrict the growth of bacteria without the use of Biocides within normal housekeeping programs. Poly Cord Belting is made from Polyurethane and is generally “Elasticated” and therefore often able to be installed where no adjustment is available & applied correctly they remain tight during their working life. The belts are made shorter than the circumference of the conveyor or drive by a percentage usually between 5% to 8% , this allows the belt to remain under tension in either a drive or conveyor application with little or no attention. Poly Cord Belts are normally Solid PU, although hollow & reinforced types are available in many diameters. All types can be joined, welded endless simply by heat and light pressure with no glue necessary. Belts can be supplied endless from Performance Conveyor Belting or as open long length for the user to weld as required. Please contact us at for further assistance.


Spiral Wound Gaskets

ISG are pleased to be able to offer Spiral wound gaskets. These are constructed as alternate plies of preformed metal windings and plain fillers that are spirally wound when compressed between two flanges. A "V" & "W" shaped crown centered in the metal strip acts as a spring, giving gaskets greater resilience under varying conditions. Filler and strip materials can be changed to accommodate different chemical compatibility requirements. If the load available to compress a gasket is limited, gasket construction and dimensions can be altered to provide an effective seal. A spiral wound gasket may include a centering ring, an inner ring or both. The outer centering ring enters the gasket within the flange and acts as a compression limiter, while the inner ring provides additional radial strength. The inner ring also reduces flange erosion and protects the sealing element. Resilience & strength make spiral wound gaskets an ideal choice under a variety of conditions & applications. Widely used in refineries and chemical processing plants, spiral wound gasket are also effective for power generation, aerospace, & a variety of valve and special applications. Wherever you need a strong, resilient seal, our spiral wound gaskets provide an effective solution. Information can be found in our ‘Technical’ section & any further assistance please enquire by email at
