The Multiquip 21595 Tee Fitting 16Mj-12Mo-16Mj is a genuine OEM hydraulic fitting designed for HTX44 and STX55 series hydrostatic ride-on power trowels. Sourced directly from Multiquip, part 21595 delivers an exact-match connection point within the hydraulic circuit, ensuring correct port sizing and thread engagement on first installation. This fitting is confirmed to fit the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 models, making it a direct solution for scheduled maintenance or field repairs on these machines.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Multiquip's original port and thread specifications, ensuring correct flow path geometry and leak-free sealing under operating hydraulic pressure.
- Exact Port Configuration — Three-port tee layout with 16Mj inlet/outlet and 12Mo branch matches the original hydraulic line routing on HTX44 and STX55 machines without rework or adapter fittings.
- Broad HTX44 and STX55 Compatibility — Verified fitment across HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 Whiteman ride-on trowel models.
- Sustained Hydraulic System Performance — A correctly seated tee fitting maintains consistent fluid distribution across the hydraulic circuit; a damaged or improperly sized fitting can cause pressure loss, erratic blade pitch control, or drive response issues.
- Pressure System Safety — In a high-pressure hydraulic system, a properly rated OEM fitting reduces the risk of joint failure, fluid escape, and associated operator hazards during machine operation.
A tee fitting is a three-port hydraulic connector that splits or combines fluid flow within a pressurized circuit. On hydrostatic ride-on trowels like the HTX44 and STX55, hydraulic circuits control both blade pitch adjustment and machine drive, so every connection point in the system must maintain a reliable, pressure-rated seal. When a tee fitting cracks, corrodes, or develops a thread defect, it can cause fluid loss, inconsistent hydraulic response, and potential damage to downstream components — making prompt replacement with the correct OEM part essential to keeping the machine operating safely and accurately.
