Key Features

• OEM-Matched Thread and Angle Spec — Manufactured to the exact 45° angle and thread standard of the original, maintaining a pressure-rated seal in concrete pump hydraulic and fluid lines.
• Direct Replacement for C30HD and LS Series — Confirmed fitment across C30HDGA, C30HDG, C30HDZ, C30HDN, C30HDNI, LS300, LS400, LS500, LS600, LS600P, LS40D, LS40TD, LS50TD, and LS60TD Mayco concrete pumps.
• Leak-Free Line Routing — A correctly seated 45° fitting allows fluid lines to change direction cleanly without stress on hose ends, preventing weeping connections under pump pressure.
• Genuine Multiquip OEM Part — Sourced directly through Multiquip's OEM supply chain and sold by DHS Equipment, an authorized distributor — not a generic hydraulic fitting substitute.
• Pressure-Circuit Integrity — On concrete pumps, a failed or cross-threaded fitting can cause line pressure loss or fluid contamination; replacing with the correct OEM part restores full system integrity.

A 45° fitting is a angled hydraulic or fluid line connector used to redirect flow between hoses, pipes, or ports at a 45-degree angle. On Mayco concrete pumps, these fittings are used throughout hydraulic circuits and fluid routing systems where a straight connection would create excessive hose bend or strain. When a fitting cracks, strips, or begins to weep fluid, pump pressure drops and the risk of contamination increases — making timely replacement with a correctly spec'd part critical to keeping the pump operating at full output.
