Groco SSC-1000 Bronze Safety Seacock Converter Engine Flush Kit 1" NPT

The Groco SSC-1000 is a cast bronze safety seacock converter and engine flush kit designed to add emergency bilge pumping capability, winterization access, and cooling system flushing to any raw water seacock. Installed on the outflow side of your engine's raw water seacock or strainer, this 1" NPT fitting integrates seamlessly into existing plumbing with no major modifications required.

The SSC-1000 features an O-ring sealed side port with a quarter-turn twist-lock quick-release plug, secured by two locking dogs for a positive seal. The bronze full-flow design is UL listed, and the valve handle is engineered to prevent accidental plug removal when in the open position — a critical safety feature during normal engine operation.

Three Key Functions:

• Emergency Bilge Pumping: With the engine running, close the seacock and remove the quick-release plug. The engine's raw water intake pump will draw excess bilge water and pump it overboard. Pair with a Groco BSA Bilge Strainer Kit to reach remote or deep bilge locations.
• Winterization: Close the seacock, remove the quick-release plug, and thread in the included service adaptor. Antifreeze can then be introduced directly into the engine cooling system via a garden hose connection.
• Cooling System Flushing: Close the seacock and insert the service adaptor. With the engine running at idle speed, dockside fresh water can be used to flush the entire raw water cooling circuit.

The Groco SSC-1000 is an essential upgrade for any inboard or inboard/outboard vessel, providing quick access to the raw water circuit for routine maintenance and a critical emergency pumping resource when it matters most.
