The Bomag 05990096 Reducing Union is a genuine OEM component designed for Bomag BM 500/15 and BM 600/15 cold milling machines. Sourced directly from Bomag, this reducing union matches the original specification for a straight, hassle-free installation. Compatible across multiple variants — including the BM 500/15, BM 500/15-2, BM 500/15 Stage V, BM 600/15, BM 600/15-2, BM 600/15 Stage V, BM600 /15, and BM 600/15 EU-Flex T4i — this part covers a broad range of BM-series cold milling configurations. When a fluid or hydraulic line connection requires a step-down in fitting size, this reducing union delivers the correct geometry and thread engagement every time.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and thread specification, ensuring correct sealing performance and pressure rating for cold milling machine fluid systems
- Direct-Fit Replacement — engineered to the same dimensions as the original, so this reducing union threads in without reworking adjacent fittings or lines
- Broad BM-Series Coverage — fits the BM 500/15, BM 500/15-2, BM 500/15 Stage V, BM 600/15, BM 600/15-2, BM 600/15 Stage V, BM600 /15, and BM 600/15 EU-Flex T4i cold milling machines
- Leak-Free Line Integrity — a correctly sized reducing union maintains full fluid pressure across the connection; an incorrect or worn fitting risks seepage that can compromise hydraulic or fluid system performance
- Verified Part Number — order with confidence using Bomag part number 05990096, confirmed against Bomag's OEM catalog for these BM-series models
A reducing union is a threaded fitting that joins two fluid or hydraulic lines of different diameters, stepping down from a larger bore to a smaller one while maintaining a sealed, pressure-rated connection. In a cold milling machine like the BM 500/15 and BM 600/15, these fittings appear throughout the hydraulic and fluid plumbing circuits where line sizes must transition cleanly. A damaged, corroded, or incorrectly sized union can cause slow leaks, pressure loss, or full line failure — any of which can take a cold milling machine out of service. Replacing a worn union with the correct Bomag OEM part restores the integrity of the fluid circuit and keeps the machine operating at full capacity.
