INNERLYNX® - Penetration Seals



INNERLYNX form a mechanical seal between pipes going through walls, floors, vaults, tanks and pipeline casings. Besides being designed to form a hydrostatic seal of up to 40 PSIG and up to 92.28 ft. of head pressure, INNERLYNX help absorb vibrations, shocks, and sound waves. Being non-conductive, INNERLYNX electrically isolate the inner carrier pipe from the penetrated structure. With this being a desired property in many applications in preventing a shorting effect from stray currents, it is particularly useful in sealing the gap between electrical conduit and the outer conduit or between electrical conduit and the opening. INNERLYNX can be installed easily and quickly by one worker with no special tools required.

Steel pressure plates are available upon request and where the electrical isolating property is not needed. Standard nuts and bolts have an anti-corrosive coating, and stainless steel bolts are also available upon request. Twelve different sizes of INNERLYNX are available for most pipe sizes with diameters from 1/2" to 100". Custom sizes can also be made. Quality control measures have been set, constantly pressure testing all styles of INNERLYNX at 35 PSIG to insure their integrity.
