The Groco SSC-1000 is a cast bronze safety seacock engine flush kit and service adapter designed to add emergency bilge pumping capability, winterization access, and cooling system flushing to any existing raw water seacock. Threaded onto any seacock with a 1" NPT fitting, this adapter transforms a standard seacock into a multi-function marine safety and maintenance hub — all without specialized tools.
Key Features:
- Quarter-turn quick-release plug — O-ring sealed side port with a twist-lock plug secured by two dogs for a reliable, watertight seal
- Cast bronze construction — Durable, corrosion-resistant bronze body built for the marine environment
- 1" NPT thread with 1" hose ID for a direct fit on standard 1" seacocks
- Overall length: 4.35"
- Includes service adapter — Garden hose-compatible service adaptor included for winterization and flushing
- Valve handle design prevents accidental removal of the quick-release plug when open
- Compatible with the Groco BSA Bilge Strainer Adapter Kit for pumping remote or deep bilge locations
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 in bilge water and pump it overboard — a valuable last-resort safety measure in a flooding situation.
Winterization: Close the seacock, remove the quick-release plug, and insert the included service adapter to connect a garden hose or antifreeze supply. Anti-freeze can be drawn directly into the cooling system.
Cooling System Flushing: Insert the service adapter and use dockside water to flush the engine cooling system with the engine running at idle speed — no dry-running risk.
The SSC-1000 installs on the outflow side of the engine's raw water seacock or strainer and is an ideal upgrade for any inboard or inboard/outboard powered vessel. For added isolation and backflow prevention, the Groco SSCV-1000 adds an integrated full-flow ball valve to this same platform.
