All Seals, Inc.

Description: Silicone rubber rolls are available for a range of applications in the industrial and residential markets. This type of Silicone rubber has excellent stretching capabilities while remaining strong enough to be elastic. Silicone rubber rolls are available in 50 to 60 durometer and can be ordered in other durometers by special request. With an average elongation of 300% and an average of 650 PSI tensile strength, Silicone rubber rolls will handle most tough medical or gasket environments and heavy alkaline and chemical resistive situations. Since silicone rubber is made of synthetic materials and is inert it makes it an excellent choice for applications where fungal growth is not permitted.

All Seals maintains extensive bun and roll stock inventories, which can be processed into sheets or rolls on our electronically controlled splitting machines very quickly. From these sheets and rolls, a variety of gasket, sealing and cushioning products can be manufactured.

Series 100 gaskets and gasketing materials are available as an allknitted wire mesh or as a knitted wire mesh over and elastomer core. The knitted wire mesh can be fabricated with .0035” (0.089) or .0045” (.114) diameter Monel or SnCuFe (tin-plated, copper-clad steel) Wire or with .005” (.127) diameter Aluminum Wire. The all metal wire mesh is manufactured by knitting several layers of mesh and forming the mesh into the size and shape. The knitted wire mesh over elastomer core is manufactured by knitting two wire mesh covers over an elastomer core, then forming the mesh to the size and shape of the elastomer core. The elastomer cores are available in Neoprene Sponge, Silicone Sponge, or Solid Silicone Tubing.

Diaphragm operated devices are essentially pistons operating within a cylinder. They transfer pressure from one sealed area to another. In the case of hydraulic and pneumatic cylinders, the moving piston is sealed off by a sealing device such as an o'ring, cup, vee packing, or a similar device. A diaphragm merely limits the stroke and provides a frictionless seal. Diaphragms generally cost less, have more tolerance range, and do not require hardened super finishes or lubrication. The function of a diaphragm is the most important factor in its design and manufacture. Simple diaphragms move from one position to another, such as pressure switches and solenoid valves. There are only two positions. In the case of modulating devices, such as regulators, the diaphragm must respond to small changes in differential pressure and the diaphragm must return to the same corresponding position. Here, the concern is with flexibility, uniform spring rate, and a minimum change in effective area.

All Seals Inc. carries a comprehensive inventory of mechanical seals for same-day shipment. Our safety stock program ensures that the seal you need is available when you need it. We specialize in hard-to-find seals and demanding applications. Our extensive network of resources enables us to locate the right manufacturer and part, every time. In the event a custom seal is required our engineers will work with you to develop a solution. Contact us for additional assistance.

Gaskets are an integral component of any device which requires the confinement of a gas or liquid. They compensate for the unconformity of mating surfaces. These surface irregularities may be minute or large depending on the purpose of the device but in all cases, the gasket is required to compensate for the difference while limiting the flow of fluid in either direction. Gaskets differ from seals in that gaskets are normally cut from sheets or rolls while seals are formed individually in their own configuration. A flat cut gasket is derived from material of specific thickness and to a configuration that is designed for a specific application
