External Mount Split Wall Sleeves

The External Mount Split Wall Sleeve is a highly versatile solution designed to seal pipe penetrations through walls, floors, and ceilings in both typical and atypical installation scenarios. Its innovative design allows for installation after cement has been poured, which makes it a valuable option for retrofitting existing structures or for use in projects where piping needs to be added to already-completed walls, floors, or ceilings. Whether the concrete has set for just 5 days or as long as 5 years, the Split Wall Sleeve can be installed quickly and easily around existing piping, saving both time and effort during construction and retrofit projects.

One of the primary benefits of this wall sleeve is its ability to replace or back up existing wall penetrations that have inadequate sealing capability. In these cases, the sleeve provides a more reliable, long-lasting seal, preventing potential issues like leaks or water ingress. When paired with Innerlynx® modular mechanical seals, the External Mount Split Wall Sleeve offers a high level of protection, capable of withstanding up to 40 psig or 92 feet of head pressure, making it suitable for a wide range of applications, from water treatment plants to industrial piping systems.

Each sleeve comes complete with anchor bolts and hardware for secure and easy installation onto both your pipe and the concrete form, simplifying the overall process. The sleeve is available in multiple materials to meet different project needs and environmental conditions: Gal-vo-plast® Steel, Stainless Steel, and Plain Steel. These options ensure the product’s adaptability to various installation environments, offering durability and long-term performance in even the most demanding conditions.
