WATER / AIR CONNECTION

551 707 02C WATER / AIR CONNECTION This fitting serves as a secure junction point within the compressed air circuit, often located where the main air hose connects to the rock drill body. Its primary job is to channel high-pressure air for functions like flushing rock cuttings from the drill hole. A solid, sealed connection here is fundamental to the entire pneumatic system's integrity and the drifter's performance.

An air leak at this connection directly impacts drilling efficiency. Reduced air pressure results in poor flushing, which slows down the rate of penetration and significantly increases the risk of the drill steel getting stuck. Even a small, persistent leak forces the rig's compressor to work harder, leading to higher fuel consumption and premature wear on major components.

The most common sign of failure is a distinct hissing sound of escaping air near the drifter. During routine checks, visually inspect the fitting for cracks or heavy corrosion. If a leak is suspected, a spray of soapy water will quickly reveal its source with bubbles. Always ensure the air system is fully depressurized before attempting to tighten or replace this connection.
