Functional Fluid, Lubricant, Grease (including Additives)

gpd chemicals are designed to meet OE specifications and standards. Using the correct chemical for your application will ensure proper function. gpd recommends properly flushing all chemicals from the A/C system before recharging.

Diesel Fuel Supplement +Cetane Boost is a winterizer/antigel that is used in the cold winter months to prevent fuel gelling and keep fuel-filters from plugging with ice and wax. When temperatures drop, paraffin (wax) in ULSD fuel will gel stopping fuel from flowing through the engine, and water in the fuel can freeze on the facings of fuel-filters, blocking fuel flow. It provides trouble-free winter operation for diesel fuel. Diesel Fuel Supplement +Cetane Boost is intended for use only during cold winter months when temperatures drop below +30F. Use Diesel Kleen +Cetane Boost (in the silver bottle) for peak performance in non-winter months. If your vehicle will not start or gain power in cold temperatures, use Diesel 911 (in the red bottle).

LUBEGARD(R) Assemblee GooTM is formulated for use as an assembly aid and lubricant for virtually any assembly application (including engine). It facilitates the assembly process by holding components such as needle bearings and hydraulic seals in place, helping to achieve a faster, trouble-free rebuild. Assemblee GooTM also provides the initial lubrication for the moving parts on the first start-up after service, preventing wear and scoring. It will not melt at shop or workbench temperatures and provides either light or firm tack as your assembly requires. Yet, it dissolves and becomes soluble in transmission fluids at operating temperatures, without clogging filters or solenoid valves. LUBEGARD(R) Assemblee GooTM is dyed to eliminate misdiagnosing leaks.

Provides corrosion protection for entire air brake system and disperses water.

K-Seal HD (heavy duty) for large capacity cooling systems such as trucks/tractors, industrial, AG, and RV engines.
K-Seal HD is the best-selling trade trusted permanent total coolant leak repair. The super concentrated formula not only permanently repairs blown head gaskets it also seals leaks in the radiator, heater core, head, block, water pump and freeze plugs. K-Seal HD mixes with all antifreeze / coolant so there is no need to drain or flush the system before or after treatment, and just one bottle is all you need for engines up to 60 quarts. Simple to use simply Shake, Pour and Go! K-Seal HD can be added via the radiator, top hose or via the expansion tank provided it is safe to do so.
K-Seal HD uses a unique ceramic formula and contains NO sodium silicate or liquid glass so it will positively not clog any part of the cooling system. K-Seal HD also works on Hard Plastic and has been independently tested at Brighton University and conforms to the American Standard ASTM D-3147 for Stop-Leak Additives for Engine Coolants. Guarantee - Once we make the repair it is for the life of the engine.
