GAL-VO-PLAST® WALL SLEEVES
Specially Developed Proprietary Coating System
to Replace Galvanizing

WALL SLEEVES
Protect your investment and use APS wall sleeves to provide a better seal than a core drilled hole. In the

absence of wall sleeves, mechanical/utility piping vibration can cause costly wall damage. In addition, wall sleeves make it easy to repair piping without damaging the wall.

APS wall sleeves are designed to mate with the Advance INNERLYNX seals for leak free performance. APS standard length is 12 inches, however, we can customize any size wall sleeve, keeping in mind a 6 inch minimum is required. Each model is available with a water stop that anchors the sleeve to prevent thrust movement and insure positive water sealing. APS standard water stops are centered, unless otherwise specified.

Gal-vo-plast® Wall Sleeves vs. Galvanized Wall Sleeves

Two wall sleeves with two different types of protective coatings were submitted for testing at an independent lab. This test consisted of a 500-hour exposure test (equal to two years) in a B 117 salt fog chamber. This test has been used to a considerable extent for the purpose of comparing different materials and finishes.

One sample had hot dipped galvanized coating and the other had Gal-vo-plast® coating. The coatings were of uniform thickness and showed good adhesion.

After testing, the submitted wall sleeves were removed from the salt fog chamber for visual examination.

The picture on the left shows the Gal-vo-plast® wall sleeve after testing. Visual examination revealed no indications of oxidation on any of the exposed surfaces of the Gal-vo-plast® coating.

The picture on the right shows the galvanized wall sleeve after testing. Visual examination revealed considerable oxidation of the galvanized coating on all exposed surfaces which is covered with white zinc oxide
