LTP Locking T-seal

Seal & Design has been working with several hydraulic equipment manufacturers in implementing the LTP locking T-seal.  The advantage of having the T-seal backup device lock into the elastomer seal, is a tremendous costing saving during installation, and significantly reduces any damage to the back-up rings during assembly.

Locking T Piston Seals are designed for bi-directional pressure applications and specifically for compression type dynamic sealing.  The backup rings, are typically made from nylon, Teflon, or Peek (for extremely high pressures), and standard elastomer material are Nitrile (Buna-N) and Viton.

CHEMRAZ® 505

Chemraz 505 is a universal compound having the broadest range of chemical resistance on the market. Chemraz 505 is ideal for processes taking place in subzero temperatures as well as for use in multi-substance plants or in mixed media.

Seal & Design is a leading distributor for the Chemraz product line, and has had many successes solving customer issues with other competitive perfluoroelastomers.

Klinger Gasket Material

Klinger offers a variety of sealing materials, including compressed fiber sheet such as Klinger C4401 and C4433, flexible graphite sheet from pure HL style to SLS with its .002″ thick 316ss foil insert, and PTFE products such as the top-chem chemical sheets (advertised as “maximum sealing with minimum creep”), soft-chem expanded PTFE sheet, and Sealex, 100% pure PTFE joint sealant.

Seal & Design is a stocking distributor for the Klinger product line, please contact us with any questions regarding your gasketing needs.

PORON Microcellular Urethanes for Gasketing and Sealing

PORON® Microcellular Urethane foams offer a broad range of design solutions for gasketing, sealing, vibration and sound dampening and energy absorption. PORON® materials exhibit low compression set  and low outgassing making these high performance urethane foams ideal for applications in communications, automotive, electronic, and other industrial devices.

Seal & Design is a stocking distributor for PORON®,  and has the ability to fabricate to your specifications.

Hallite New Type 844 Wiper

Seal & Design now offers the Hallite type 844 wiper.  The double lip design of the Hallite Type 844 has a special feature of a flap on the external wiping lip which covers the gland housing. This flap prevents the water/slurry trap occurring which is so common with conventional wipers and thereby stops contamination from getting around the outside of the wiper.

The Hallite wiper showed its ability to clear surface frost/ice whilst operating at temperatures down to -45°c and also working in environments of 110°c radiated heat.  See video below:

New Teflon Encapsulated O-Ring Page

teflon encapsulated o-ringSeal & Design has updated it’s Teflon encapsulated o-ring page, and included a Adobe PDF link giving you the different options for core and jacket materials.  Teflon Encapsulated O-rings combine the qualities of Teflon (PFA/FEP) with Viton® or Silicone rubber. They have an outer jacket of teflon protecting the resilient core from virtually all chemicals.

The rubber core is totally encapsulated by Teflon (PFA/FEP) and this unique combination enables encapsulated o-rings to give maximum protection against leaks in a wide range of sealing applications. Teflon (PFA/FEP) has always been recognized as an ideal, chemically resistant, sealing material but it lacks elasticity. The Viton® or Silicone rubber core provides this missing element of memory, together with exceptionally good resistance to compression set, even at high temperatures.
