Key Features
- OEM-Grade Thread Integrity — Manufactured to the exact 1/4-18NPT thread specification, ensuring full engagement and a pressure-tight seal without thread damage on installation.
- 90-Degree Elbow Configuration — The right-angle geometry routes fluid or pneumatic lines cleanly in space-constrained areas of the pump, matching the original routing path of the ST30.
- Confirmed ST30 Fitment — Purpose-built for the Multiquip ST30 concrete pump; matches the OEM port size and connection type for a direct, straightforward swap.
- Leak-Free Pump Operation — A correctly seated NPT fitting maintains system pressure integrity; a failing or cross-threaded fitting can cause fluid loss, pressure drop, and unplanned pump shutdowns.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM component under part number EM16425, carrying the full backing of Multiquip's parts program.
A 1/4-18NPT x 90-degree fitting is a threaded elbow connector used to join fluid or hydraulic lines at a right angle within the pump assembly. The NPT (National Pipe Taper) thread form creates a pressure-tight mechanical seal as the fitting is torqued into the port, making it critical to maintaining system integrity. When this fitting cracks, corrodes, or develops thread damage, it can allow fluid to escape under pressure, leading to pressure loss, contamination, and pump malfunction.
