Holedall Grooved End Stem

Application

• Recommended for use on most one and two wire braid reinforced hoses, fiber reinforced (braided or spiraled) with or without helical wire such as: oil and suction discharge hose, barge and dock loading and unloading hose as well as L.P. gas hose, anhydrous ammonia hose, acid chemical hose and air and water hose.

Use

• Designed for hose ID’s 1-1/4”“ – 10”. The ferrule size depends on the hose OD.

Features

• Tubular type
• The coupling system requires no bolts and results in a clean coupling with no protrusions.
• The Holedall coupling provides long-lasting efficiency and safety.

How it works

• The hydraulic swaging of the coupling to the hose is accomplished by pushing the ferrule through a die which reduces the ferrule OD, thus providing a 360° uninterrupted compression band around the hose.
• A hydraulic ram is the only piece of machinery necessary to accomplish the coupling. Rams are available in five different sizes- 15,25, 50,100 and 350 ton – these rams will accommodate dies and pushers of various sizes so that hoses up to 10” in diameter may be coupled.
• Couplings can be swaged or crimped.
