Holedall Beveled End Stem for Welding

Application

• Recommended for use where additional retention is required due to higher working pressures or end pull, 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.
