BOCHU Spring Seal Positions and Sizes
BOCHU BOCI spring seals are replacement sealing components for compatible BLT laser cutting heads. The collection includes standard laser spring seals and second-lower spring seals in multiple sizes and model-specific BOCHU part numbers. Seal position and dimensions determine compatibility.
How to Select the Correct Spring Seals
Confirm the installation position, outer and inner dimensions, cutting-head model and original part number. A second-lower seal should not be substituted for another optical position. If the old seal is damaged or unmarked, send a dimensioned photo together with the head nameplate and packaging label.
