GROCO 1.25-Inch NPT Bronze In-Line Ball Valve

The GROCO IBV-1250 in-line ball valve provides a compact full-flow shutoff for marine fuel or water plumbing. Its female NPT connections let the valve install directly between threaded system components without an added flange assembly. The square opening in the handle can accept a standard ratchet when the valve is difficult to reach or needs extra leverage. A selectable handle position helps the installer orient the operating sweep around nearby hoses, bulkheads, and equipment.

The IBV-1250 uses a C83600 bronze body with stainless-steel handle and hardware and a solid chrome-plated brass ball rather than a hollow ball. PTFE seats and seals support smooth operation, while the bonding attachment provides a connection point when required by the vessel's electrical-bonding plan. Its full-flow passage is intended to minimize restriction through the shutoff. The valve carries a 400 WOG rating and is UL listed for fuel or water service. This size also includes a grease fitting that can be used for lubrication with the valve open or for draining during service.

• Female NPT connections for in-line installation
• 400 WOG pressure rating
• Ratchet-compatible handle for difficult access
• UL listed for fuel or water service
• PTFE seating and sealing surfaces

Install the IBV-1250 with the handle accessible through its full travel and with enough clearance to use a ratchet if that feature may be needed later. Threaded connections should be assembled with sealant appropriate to the fluid and fitting materials, and supported piping should not place side load on the valve body. After pressurizing the system, inspect both threaded joints and cycle the valve several times to confirm smooth shutoff.
