JP-1 Cooling System Pressure Regulator

The JP-1 Cooling System Pressure Regulator is a compact, all-stainless solution designed to precisely control water inlet pressure without the need for an overboard relief line.

Unlike conventional pressure relief systems that dump excess water once a threshold is exceeded, the JP-1 regulator operates normally open and progressively closes as inlet pressure rises, maintaining a stable, controlled pressure to your cooling system. This closed-loop approach simplifies plumbing, reduces unnecessary water discharge and delivers more consistent inlet conditions.

The regulator is supplied pre-set to 20 PSI and is fully adjustable to accommodate operating demands. An integrated pressure gauge port allows real-time monitoring and precise tuning for users who want to dial in their system.

Constructed entirely from stainless steel, the JP-1 Cooling System Pressure Regulator is built for high-pressure marine environments while maintaining a compact footprint for clean and reliable installations.
