GROCO 3/8" NPT Stainless Steel In-Line Ball Valve

The GROCO 3/8" NPT Stainless Steel In-Line Ball Valve is a precision fluid control component designed for marine, automotive, and industrial hydraulic systems where reliability and corrosion resistance are essential. This valve is ideal for applications such as custom fuel systems, hydraulic brake lines, and high-performance cooling circuits, providing dependable shutoff performance in demanding environments.

Constructed from marine-grade stainless steel, this valve is resistant to saltwater corrosion, ethanol fuel exposure, and thermal cycling, which can degrade standard brass or steel valves over time. Its compact design and NPT threading facilitate easy integration into tight spaces, making it a preferred choice for mechanics and fabricators who need to isolate flow without adding bulk.

Fabricators, restoration shops, and track enthusiasts will find this valve particularly beneficial when plumbing custom fuel systems, water-to-air intercooler loops, or auxiliary cooling circuits. The 3/8" NPT female threads are compatible with standard plumbing and hydraulic fittings, ensuring seamless integration into custom manifold assemblies or aftermarket installations.
