GROCO 1.25-Inch 1-Inch Side-Port Safety Seacock

The GROCO SBV-1250 is a safety seacock with side port for marine intake and discharge plumbing where a positive hull-side shutoff is important. The side port that accepts an NPT accessory such as GROCO's safety-seacock service components is especially useful when the valve must be fitted into an existing installation with limited room around the hull connection. Full-flow geometry helps keep the valve from becoming an unnecessary restriction in the line. Its design gives the operator a direct way to isolate the connected line for service, winterization, or an emergency without dismantling the plumbing.

PTFE seating surfaces provide the valve seal, and the base includes a bonding point for installations where the vessel's bonding plan calls for one. Serviceability is part of the design, allowing routine attention to the valve without treating it as a disposable fitting. GROCO builds the SBV-1250 around a C84400 bronze body with a stainless-steel ball and stem. The handle is designed so a standard ratchet can assist operation when access is awkward or a valve has become difficult to move by hand.

• Two driver ports allow handle relocation
• Serviceable while installed
• Side port supports service or emergency-pumping accessories
• Full-flow valve design
• Ratchet-compatible handle for hard-to-reach installations

Before bedding the SBV-1250, confirm that the thru-hull, flange, hose direction, and handle sweep all line up without forcing the connected plumbing. Fasteners and backing support should be appropriate for the hull structure, and the completed connection should be checked for leaks before the boat returns to normal use. Exercise the valve periodically so it remains familiar and free-moving rather than discovering a stiff handle only when isolation is urgently needed.
