Aftermarket Sealco Valves

Fleet Products offers a wide range of aftermarket Sealco-style valves engineered to match the performance, flow rates, and fitment of the original Sealco designs—at a more cost-effective price point. These valves are built to OEM-equivalent standards for fleets that need reliable air brake performance without compromising safety or system integrity.

Available in multiple configurations including relay, ratio relay, spring brake, control line, and emergency release valves, our aftermarket selection fits most heavy-duty trucks, trailers, buses, and converter dollies. Each unit is fully tested for pressure consistency, crack response, and leak-free operation in demanding conditions.
