Reliable Waterproof Protection

This mixing valve and pipe seal kit is designed to create a watertight seal around shower valves and pipe penetrations, effectively preventing water leakage and protecting wall structures from moisture damage.

Durable Rubber Gasket Construction

Made from high-quality rubber combined with polyethylene non-woven waterproof membrane, the seals offer excellent flexibility, durability, and long-term resistance to wear, cracking, and moisture exposure.

Thin Profile – Minimal Build-Up

With a slim membrane design, this seal kit adds minimal thickness to the wall assembly, ensuring a smooth surface for tile installation without affecting alignment or finish quality.

Easy & Hassle-Free Installation

Pre-formed round seals fit securely around mixing valves and pipes. Simply install with thin-set mortar as part of your shower waterproofing system—no special tools required.

Wide Compatibility

Compatible with standard shower and bathtub valve openings and pipe outlets. Ideal for use with waterproof boards, cement backer boards, and tile shower systems in residential or commercial bathrooms.
