  • This kit includes the Lincoln 5852 hydraulic coupler and the Lincoln 62028 6" extension tube, giving you everything needed to assemble the coupler-and-extension combination in one purchase.

  • This assembly is rated for a maximum operating pressure of 6,000 PSI, making it suitable for high-pressure grease gun applications commonly found in heavy-duty lubrication work.

  • This coupler uses a 1/8" NPT connection, so your grease gun hose or fitting will need to be 1/8" NPT to mate properly with this assembly.

  • The 6" extension tube allows you to reach grease fittings in tight, recessed, or otherwise hard-to-access locations where a standard coupler alone would not reach, reducing the need to reposition equipment during lubrication.
