Multiquip 19088 Brass Fitting 1/2MP 4 Compression

The Multiquip 19088 Brass Fitting 1/2MP 4 Compression is a genuine OEM component designed for JTO-Series and HTN-KOHLER/ONAN/HONDA ride-on power trowels. Sourced directly from Multiquip, this fitting meets the exact material and dimensional standards of the original part. It is a direct replacement for machines requiring a 1/2 male pipe to 4-compression fitting, ensuring a secure, leak-free connection in the hydraulic or fluid line circuit. Confirm your model code against the fitment list before ordering to ensure compatibility with your specific machine configuration.

Key Features

• Genuine OEM Brass Construction — Machined from brass stock to match the original fitting's thread form and compression seat, delivering the corrosion resistance and sealing integrity expected on hydraulic and fluid circuits.
• 1/2 Male Pipe to 4-Compression Configuration — Purpose-built thread and compression spec allows this fitting to seat and torque correctly into the existing port without rework or adapter additions.
• Verified Fitment for JTO and HTN Series — Confirmed for JTO-Series and HTN-KOHLER/ONAN/HONDA Whiteman ride-on power trowels, covering multiple engine configurations within those families.
• Leak-Free Fluid Line Integrity — A correctly seated fitting maintains consistent fluid pressure and flow, keeping the trowel's hydraulic or lubrication circuit functioning as designed. A failing or cross-threaded fitting can result in fluid loss, erratic blade control, or unplanned downtime.
• Fluid System Safety — On ride-on trowel hydraulic circuits, fitting integrity is directly tied to operator control response. Using the correct OEM-spec fitting eliminates the risk of mismatched thread forms that can back out under pressure.

A brass fitting of this type serves as a transition connector between pipe-threaded ports and compression-style tubing within the machine's fluid circuit. It forms a pressure-tight seal by combining the male pipe thread engagement at one end with a ferrule-compression grip on the tubing at the other, allowing fluid to pass between system components without leakage. When a fitting of this type corrodes, cracks, or strips, it compromises line pressure and can introduce air or contaminants into the circuit, affecting both performance and control.
