Multiquip 366437 Bulkhead Fitting #4 JIC

The Multiquip 366437 Bulkhead Fitting #4 JIC is a genuine OEM hydraulic fitting designed for SP, PS, and CS series pavement saws. As a factory-sourced component, part 366437 delivers the exact thread form, sealing geometry, and material specification required by Multiquip engineering for these machines. Confirmed fitment spans a wide range of models including SP303516, SP303520, SP303526, SP303530, PS403016, PS403020, PS403026, PS403030, PS706016, PS706020, PS706026, PS706030, PS706036, SP403016, SP403020, SP403026, SP403030, SP706016, SP706020, SP706026, SP706030, SP706036, CS403016, CS403020, CS403026, CS403030, CS706016, CS706020, CS706026, CS706030, and CS706036. Sourcing a genuine OEM fitting like the 366437 eliminates the risk of thread mismatch or hydraulic leakage that can result from using an incorrectly rated substitute.

Key Features

• Genuine OEM Thread Integrity — Manufactured to the exact #4 JIC thread specification called out by Multiquip, ensuring a leak-free hydraulic connection without reworking fittings or adapters.
• Bulkhead-Mount Design — Built for panel or bulkhead installation, allowing hydraulic lines to pass cleanly through a partition with a secure, vibration-resistant seal suited to saw operating conditions.
• Broad Saw Series Compatibility — Confirmed for SP, PS, and CS pavement saw models across multiple blade and engine configurations, covering both Street Pro and standard pavement saw platforms.
• Hydraulic System Reliability — A correctly seated bulkhead fitting maintains consistent hydraulic pressure to blade drive and water systems; a failed or leaking fitting can cause pressure loss and uncontrolled fluid discharge.
• Fuel and Fluid System Safety — Proper JIC sealing at the bulkhead point prevents hydraulic fluid from contacting hot engine or exhaust surfaces, reducing fire and contamination risk on active worksites.

A bulkhead fitting allows a hydraulic or fluid line to pass through a structural panel or housing wall while maintaining a sealed, pressure-rated connection on both sides. The #4 JIC designation specifies the thread size and 37-degree flare seat angle that governs how the fitting mates with the corresponding hydraulic line end — an incorrect seat angle or thread pitch will not seal under pressure. On pavement saws, bulkhead fittings are used to route hydraulic lines between external and internal sections of the machine frame; when a fitting cracks, strips, or corrodes, the result is hydraulic fluid loss, pressure drop, and potential damage to downstream components including the blade drive circuit.
