UHANBUT Engine Air Valve Pressure Hose Brass

Description

Product Overview

The UHANBUT Engine Air Valve Holder Pressure Hose is engineered for accurate cylinder pressure testing and valve spring compression. Constructed from high‑grade rubber, the hose offers exceptional flexibility and resistance to kinking, while the brass joints deliver wear‑resistant, corrosion‑proof durability. Measuring 22.83 inches in length with a 0.46‑inch diameter, the hose fits standard M12 and M14 spark plug threads, making it compatible with a wide range of gasoline engines, including LS series, trucks, and marine applications. The complete kit includes a ball valve and standard brass connectors for quick setup.

Usage

Designed for professional mechanics and serious DIY enthusiasts, this tool excels in diagnosing cylinder leaks, testing valve seat integrity, and compressing valve springs safely. Install by removing the spark plug, threading the hose into the plug hole, and applying up to 300 psi (20 bar) of pressure to isolate abnormal cylinder behavior. Its lightweight design (3.2 oz) and ergonomic fittings allow for prolonged use without fatigue, whether in a garage, workshop, or on‑site service environment.
