As the description implies, these extensions are more robust than the standard Cleanshot extension. They comprise an inner fluid tube within the larger outer protective sleeve. So are less prone to damage without adding excessively to the weight. Bottom line is they will last longer!
The inlet and outlet threads are the standard Graco 7/8" UNF as used on their spray guns, so can be used with a Cleanshot valve or any spray gun, knuckle joint or tip body with that thread.
Extensions can be used in combination to a maximum recommended length of 4.25 metres.
Pressure rated to 3,600 psi (248 bar)
