We specialize in manufacturing high-performance pneumatic valves for heavy-duty Eaton Fuller transmissions, including the A-5000 Slave Valve, K-3331 Splitter Valve, and A-4740 Air Filter Regulator.

Built to strict OE-equivalent quality standards. Our production line was originally constructed for OE component manufacturing, with fully proven tooling and processes. Valve bodies are impregnated and anodized, fitted with upgraded seals. Automated production minimizes early failures and ensures batch consistency. Our valves match OE specifications without brand markup, delivering dependable performance for North American heavy-duty operators. Local inventory in Katy, TX enables fast shipping for small and bulk orders alike.

We offer volume-tiered pricing and can provide our price sheet. We accommodate small shipments, so you avoid supplier delays even for low-volume purchases. Active accounts qualify for quarterly rebates based on total purchase volume to reduce your net cost.

Every valve is precision-engineered to cut costly truck downtime and improve operational efficiency. We serve single-truck owners, repair shops, and large commercial fleets.
