ProTek U-Bolts

APP’s thermoplastic-coated u-bolts have a low coefficient of friction, restrain steel pipes and prevent metal-to-metal contact and abrasion.

APP’s ProTek U-Bolts are in stock and combine the strength and simplicity of a u-bolt with our advanced polymer technology. They successfully restrain the pipe while shielding it from metal to metal contact and rough abrasion from pipe movement. The ProTek coating is strong enough to withstand high compressive loads and harsh environmental conditions, but has a low coefficient of friction to seamlessly cradle the pipe.
