Rotary Drilling Hose

Rotary drilling hose also called Kelly hose. Drilling hose and Vibrator Hose often carries high-pressure drilling liquids from the top of the mud standpipe to the rotary swivel. Rotary hose, especially slim hose, is often used on small or medium-size drilling rigs such as water well operations, water well, water well core drill and other applications. Flexible rotary/drill hose can carry mud or air.

Our rotary hose is often equipped with API end fittings and available for 1500psi to 7500psi operating pressure. The lift eyes on the ends are designed to prevent kicking or crushing when handling.
