Key Features
- Genuine OEM Conformity — Manufactured to original Genie specifications, ensuring dimensional accuracy and material consistency for this union tee fitting.
- Direct OEM Replacement — Designed as a drop-in replacement that connects and seats correctly in the original port positions without rework.
- Broad Genie Fitment — Fits GS-series rough-terrain scissor lifts and TZ and TMZ trailer-mounted articulating boom lifts across multiple configurations.
- Fluid-Line Integrity — A properly seated union tee maintains a leak-free junction between lines; a cracked or weeping fitting should be replaced promptly to prevent fluid loss and operational interruption.
- OEM Part Number Assurance — Ordering by Genie part number 42758GT eliminates ambiguity and confirms you receive the correct fitting for your machine.
A union tee is a three-port fitting that joins two inline fluid lines and one branch line at a single junction point, allowing fluid to be routed from one source to two directions or merged from two paths into one. On Genie scissor lifts and trailer-mounted booms, this type of fitting is used to distribute or consolidate fluid flow within the circuit it serves. When a union tee fails — through cracking, thread damage, or a compromised seating face — fluid can weep or escape at the junction, causing pressure loss and requiring immediate replacement with the correct OEM part to restore proper operation.
