Correct Lubrication of the Hose Connection of the High-Pressure Cleaner

The hose connection of a high-pressure cleaner is a small component with a big impact on service life and reliability. On stainless steel parts, friction, pressure and repeated assembly can lead to cold welding, making threaded connections difficult to release and, in the worst case, permanently damaged.

For this reason, the connection should be greased with the right lubricant before use. DYNAJET recommends an anti-seize assembly paste, also known as hot screw compound. It is designed to reduce metal-to-metal adhesion and to remain effective even under high pressure and high friction. This helps keep hose connectors movable and supports safe, practical maintenance in everyday work.

This topic is especially relevant for professional users who regularly assemble and disconnect high-pressure hoses and accessories. Stainless steel offers excellent durability, but its passive layer alone is not enough to prevent cold welding in every situation. A suitable anti-seize paste adds a dry lubrication film that improves separation of the parts later on and reduces the risk of expensive thread or connector replacement.

In practice, the rule is simple: use anti-seize assembly paste whenever stainless steel hose connections are assembled. Apply it carefully to the connection surfaces and threads so the joint can be tightened and loosened as intended. For operators, service teams and workshop staff, this is a small step that supports dependable operation and helps preserve the condition of high-pressure cleaner accessories over time.
