The Bomag 05558423 T-Piece is a genuine OEM fitting designed for a wide range of Bomag tandem rollers, pneumatic tyred rollers, and cold milling machines. Sourced directly from Bomag, this T-Piece carries the exact geometry and material specification required for a straight-swap installation with no guesswork on compatibility. This component is confirmed to fit models including the BW 174 AD, BW 184 AD, BW 170 AD, BW 180 AD, BW 174 AC, BW 27 RH, BW 24 RH, BW 154 ACP-4, BW 151 AC-4, BW 161 AC-4, BW 27 RH-4i, and BM 500/15-2 and BM 600/15-2 cold milling machines, among others. Ordering by part number 05558423 ensures you receive the correct OEM component for your specific machine.
Key Features
- Genuine OEM Construction — Manufactured to Bomag's own material and dimensional specifications, ensuring the T-Piece delivers the same flow characteristics and pressure ratings as the original fitting it replaces.
- Direct-Swap Installation — Matches the original port sizing, thread form, and branch angle, so this T-Piece installs directly into the existing fluid circuit without rework or adaptation.
- Broad Fitment Coverage — Compatible with Bomag BW 174, BW 184, BW 170, BW 180, BW 151, BW 154, and BW 161 tandem rollers, BW 24 RH and BW 27 RH pneumatic tyred rollers, and BM 500/15-2 and BM 600/15-2 cold milling machines.
- Leak-Free Fluid Routing — A correctly seated T-Piece maintains system pressure and prevents fluid loss that can starve downstream components, cause erratic machine response, or lead to wider hydraulic or fluid system damage.
- Verified by Part Number — Cross-referencing to OEM part number 05558423 confirms you are fitting the exact Bomag-specified component, eliminating the risk of incorrect fitment across the many variants in this family.
A T-Piece is a three-port fitting that splits or combines fluid flow within a hydraulic, coolant, or fuel line circuit. By branching a single line into two — or merging two lines into one — it directs fluid to where it is needed in the system. When a T-Piece cracks, corrodes, or develops a leak at any of its three ports, fluid pressure drops, the affected circuit loses efficiency, and surrounding components can be starved of lubrication or cooling. Replacing a failed T-Piece promptly with the correct OEM part restores circuit integrity and protects the broader system from cascading damage.
