Our ProLAST valve is powered by the T-Seal, a new and innovative technology that has better performance and reliability than pistons and diaphragms.

Unlike pistons and diaphragms, the T-Seal is one piece, making it easy to maintain and more dependable. It features the industry's largest bypass and a tamper-proof GPF. Without natural rubber components, it lasts up to three times longer than the industry standard. This cuts down on maintenance time and costs.

Thanks to its revolutionary design, the T-Seal is 90% more water efficient than the industry standard, setting it apart from the competition. With greater reliability, easier maintenance, and better performance, the T-Seal is the new standard.
