GN 109 Fluid Level Markings / Special Lengths (Special Order)



For the series with dipstick shown above, a shortening and / or the attachment of level markings can be ordered with the service GN 109. The dipstick is shortened to the length l₁ and the marking notches are milled at l₂ or l₃, making them easily visible. The max. length l₁ is specified in the respective series. The length specifications l₁ to l₃ refer to the contact surface without seal, with a tolerance of ±1 mm to be taken into account. For critical applications, the seal must be taken into consideration with a thickness of up to 2 mm, depending on the series. If required, more than 2 notches may be inserted on request, which are then specified by appropriate details on the position (l₄ ... l_x). Furthermore, texts such as MAX / MIN may be laser-engraved in addition to or instead of the notches by submitting the appropriate template. The fluid level markings / special lengths GN 109 are to be ordered as a separate item in shopping cart step 1 under note.
