Overview – BEND JOINT 20 S1031-20 Series
S1031-20 is the CUMMINS part number for this BEND JOINT 20, fitted in Cummins engine hydraulic and tube line connections. We keep the series in our catalogue and can quote it with or without related parts.
Parts Characteristics
S1031-20 is the CUMMINS bend joint used to change the direction of hydraulic or tube lines, formed with the original bend angle and thread size for a direct fit in the line route. The body is machined from the original material grade and the sealing faces are finished to the OEM surface, so the joint seals without extra packings. The size 20 designation matches the line bore of the application.
Applicable Models & Applications
This bend joint is used on CUMMINS engine hydraulic and tube line connections where the original S1031-20 size applies, including fuel, oil and coolant circuits with a 90 degree route change. Confirm the thread size and the line bore against the joint removed from your engine before ordering. The related S1040A-20, S1047A-20 and S934-20 cover the other bend configurations in this series, and we can confirm the correct joint from your line layout.
Maintenance & Replacement
Clean the thread and the sealing face before assembly, and tighten the joint to the specified torque without over-tightening the body. Check the joint at each service for weeping around the threads and for corrosion on the body. When replacing, fit the joint with new sealing washers or O-rings as specified, and re-torque after the first hours of running.
