Putzmeister Spare Parts SCREW MOUNTING COUPLING 5.5" 524948

This 5.5-inch screw mounting coupling is a genuine replacement component built exclusively for Putzmeister concrete pump pipeline assemblies, part reference 524948. Cast from high-grade ductile iron with uniform hot-dip galvanized finish, it delivers robust anti-rust performance for long-term site use under wet, abrasive concrete working conditions.

It features dual bolted screw fastening lugs with precision threaded mounting holes, eliminating loose pipeline joints during high-pressure concrete delivery. The inner circular sealing groove matches standard 5.5-inch pump pipe flanges perfectly, locking pipe ends tightly to prevent grout leakage at connection points.

Designed for quick field installation without specialized tools, the symmetrical split ring structure allows technicians to mount or detach the coupling rapidly during pipe maintenance or layout adjustments. Each lug’s thickened casting reinforces load-bearing capacity to resist vibration and shock from continuous pump operation.

This OEM coupling fits most Putzmeister stationary and truck-mounted concrete pump models that adopt 5.5-inch delivery pipe specifications. Its standardized dimensional tolerance aligns with original factory assembly standards, ensuring seamless interchangeability with worn-out old couplings without pipe modification.

For heavy construction sites, this 524948 screw mounting coupling cuts downtime caused by joint failure. The durable galvanized surface withstands daily contact with concrete slurry, reducing frequent spare part replacements and lowering overall equipment operating costs for concrete pumping fleets.
