The Multiquip 49333 Brass Fitting 3/4 MNPT 3/8 FNPT is a genuine OEM component designed for WSC55 chemical spray systems, LD6 and LD6SL Whiteman ride-on power trowels, and PRX ride-on power floats. As a direct OEM replacement, this fitting is manufactured to the exact thread specification and dimensional tolerances required for a leak-free, secure connection in the original fluid system. Verified against Multiquip's parts catalog, the 49333 ensures the correct thread engagement between the 3/4-inch male NPT and 3/8-inch female NPT ports — no guesswork on fitment. DHS Equipment supplies this part direct, so you can be confident you are receiving the correct component for your machine.
Key Features
- Genuine OEM Brass Construction — Manufactured from brass for corrosion resistance and durability in fluid and chemical delivery applications where material integrity is critical.
- Correct Thread Specification — 3/4-inch MNPT to 3/8-inch FNPT configuration matches the original port sizing exactly, ensuring proper thread engagement and a secure, leak-free seal.
- Direct-Fit Replacement — Engineered to install in the same position as the original fitting, with no reworking of adjacent lines or ports required.
- Broad Equipment Compatibility — Confirmed fit for WSC55 chemical spray systems, LD6 and LD6SL ride-on power trowels, and PRX ride-on power float series.
- Fluid System Integrity — A properly sealed fitting maintains consistent flow and pressure in the spray or lubrication circuit; a failed or cross-threaded fitting can cause fluid loss, contamination, or system pressure drop that affects machine performance.
- Genuine OEM Part Number — Sourced directly as Multiquip part 49333, eliminating the risk of receiving a dimensional mismatch from a non-verified substitute.
A brass NPT reducing fitting serves as the transition connector between two sections of a fluid circuit that use different pipe thread sizes — in this case, a 3/4-inch male thread on one end and a 3/8-inch female thread on the other. This type of fitting is commonly used in spray systems, hydraulic circuits, and lubrication lines where plumbing must step down in diameter while maintaining a sealed, pressure-rated connection. When a fitting fails — whether through thread wear, cracking, or corrosion — it can cause fluid leaks that compromise system pressure and lead to equipment downtime or surface contamination on the worksite.
