The Genie 128929-300GT is a genuine OEM Black Shrink Tube, 3/4, 3:1 designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts. As a factory-sourced component, this shrink tube is manufactured to the exact material grade and shrink ratio specified for these machines, ensuring a consistent, correct-fit result every time. Compatible models include S-40 XC, S-40 TRAX, S-40 HF, S-45 XC, S-45 TRAX, S-45 HF, S-80 XC, S-80 HF, S-85 XC, S-85 HF, Z-45/25, Z-45/25J DC, and Z-45/25J Bi-Energy. Cross-reference part number 128929-300GT against your machine's parts manual to confirm it is the correct item for your unit.
Key Features
- Genuine OEM Material Grade — Sourced directly from Genie, this black shrink tube meets the exact material specification and 3:1 shrink ratio called out for these boom lifts — no guesswork on wall thickness or shrink performance.
- 3:1 Shrink Ratio for Secure Coverage — The 3:1 ratio provides a tight, conforming sleeve over irregular or stepped surfaces, locking in position without gaps or lifting edges once heat is applied.
- Correct Diameter for a Drop-In Repair — Cut to the specified 3/4 inch diameter, this tube fits the wire gauge and connector profiles used on the listed boom lifts without the need to source or size a substitute.
- Broad Boom Lift Compatibility — Fits Genie S-series telescopic booms from the 40-foot through 85-foot range and Z-45/25 articulating booms across XC, TRAX, HF, DC, and Bi-Energy variants.
- Protects Connections Against Abrasion and Moisture — A properly applied shrink tube shields wire splices and terminal connections from chafing, moisture ingress, and vibration — common causes of intermittent electrical faults on aerial lifts.
Shrink tube is used to insulate and protect wire splices, connector terminations, and bare conductors on electrical harnesses throughout the machine. When heat is applied, the tube contracts uniformly around the underlying wire or connector to form a tight, durable sleeve that resists abrasion, moisture, and vibration. A damaged or missing section of shrink tube leaves connections exposed, which can lead to shorts, corrosion, or intermittent electrical faults — making prompt replacement with the correct OEM part important for keeping electrical circuits performing as intended.
