Graco Pro-Shot™ Grease Dispense Valve, 1/4 NPT, No Coupler #242055

Graco Pro-Shot™ Grease Dispense Valve, 1/4 NPT, No Coupler #242055

The Graco #242055 is a heavy-duty Pro-Shot non-metered grease dispense valve with a 1/4-inch NPT female inlet, rated for working pressures up to 8,000 psi — the valve for professional grease systems in fleet, heavy-equipment, lube-truck, and service-shop service.

This configuration is supplied as the bare valve only: a coupler and nozzle extension are not included, so it pairs with the dispense hardware already in your system or selected separately.

How It Works & Flow Adjustment

• Pulling the trigger opens the valve and starts grease flow from the connected lubrication system; releasing it closes the valve and lets an air-operated grease pump stall against system pressure
• Flow is adjusted at the top of the valve: turn the lower adjustment nut inward for more flow, outward for less, then secure the setting with the locking nut
• Always relieve system pressure before disconnecting, cleaning, or servicing the valve or any connected grease equipment

Fitment & Setup

This is the bare valve configuration — coupler and nozzle extension are not included, so it pairs with dispense hardware already in the system or selected separately. Confirm your inlet size (1/4 in. vs 3/8 in. NPT) and trigger style before ordering. Graco service kit #243446 supplies the internal wear parts for this valve.
