PTFE Products

Polytetrafluoroethylene (PTFE) also known as Teflon® is a synthetic fluoropolymer of tetrafluoroethylene. Invented by DuPont, PTFE can be modified and shaped for use as a gasketing material with strong chemical resistance properties.     Advantages of using PTFE include: Not affected to most chemicals. Can be used at temperatures up to 500°F (260°C). The lowest coefficient of friction […]

Silicone vs EPDM

EPDM EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber commonly used in automotive and constructive industries but has a disadvantage of having a lower heat resistance. Silicone Silicone is an inorganic polymer used in many industries and applications with the advantage that it can withstand extreme temperatures and keep its physical properties. Silicone is […]

Viton® O-Rings

Viton® (fluorocarbon rubber, FFKM) has excellent resistance to high temperatures, ozone, oxygen mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals making it a good choice for an o-ring material. Viton® is a synthetic rubber and fluoropolymer elastomer, which is commonly used in O-rings and molded or extruded products. There are […]

O-Ring Inspection Equipment

In many critical applications (including automotive, aerospace, and life support, among others), 100% dimensional inspection of o-rings is often required. Seal & Design has a host of inspection machines that are dedicated to 100% inspection of o-rings and other seals, to ensure each individual part meets all drawing dimensions and other measurable specifications. Also called […]

Peek high performance plastic

PolyEtherEther-Ketone, or PEEK, is a high performance thermoplastic material that offers chemical and water resistant properties to seals. Peek seals are manufactured with peek material, and operate at much higher temperatures than other seals.  Seal & Design peek seals can be used consistently to a temperature of 500F without losing any physical properties, and since […]

Aflas O-rings and Gaskets

As a copolymer of tetrafluoroethylene (TFE) and propylene (P), TFE/P provides a unique combination of chemical, heat, and electrical resistance. Chemically, TFE/P resists both acids and bases, as well as steam, amine-based corrosion inhibitors, hydraulic fluids, alcohol, and petroleum fluids. TFE/P is also resistant to ozone and weather. TFE/P typically retains its remarkable chemical resistance […]

Explosive Decompression

Explosive Decompression(ED) or Rapid Gas Decompression(RGD) is a structural failure, a condition that occurs due to gas permeation or dissolution into the seal material. When system pressure decays quickly, the entrapped gas expands, rupturing the o-ring. Explosive decompression may cause blistering, internal cracking and splitting of parts. Seal & Design has compounds available in EPDM, […]

Genuine Viton®

Today’s industry sometimes operates under extreme conditions. Heat, aggressive media, corrosive gasses and mechanical stress require the utmost performance from your seals. Extreme requirements demand quality assurance and the best materials, in those cases Genuine Viton®, the fluoroelastomer made by DuPont Performance Elastomers is the solution. If safety and quality assurance are a must, Genuine […]
