Modular Mechanical Seals

APS offers a faster pipe sealing method than your everyday caulk, grout, or mastic with USA manufactured Innerlynx® Modular Mechanical Seals. Innerlynx® are used in a systematic approach for installers to easily seal the annular space between the carrier pipe and the ID of a wall penetration.

Innerlynx® are also designed to absorb vibrations, shocks and sound waves and act as a sound dampener while electrically isolating the carrier pipe from the penetrated structure.

Innerlynx® are made from synthetic rubber with industrial strength U.S. manufactured pressure plates and are available in more sizes than offered by any other U.S. manufacturer. APS offers 21 different sizes for all pipe diameters ranging from 1/2″ to 144″ and form a hydrostatic seal up to 40 psig and up to 92.28 feet of head pressure. Innerlynx are available in five different types for various applications such as:

Wall Sleeves

Advance Products and Systems offers four types of wall sleeves: Carbon Steel, Stainless Steel, Gal-vo-plast® coated steel, & HDPE lightweight Infinity® wall sleeves.
