Centennial Bullet U-Bend Fittings accommodate pipe in 1" and 3/4" diameters and are the narrowest U-bend fiitings on the market today. The smaller diameter of these fittings reduce installation costs in two significant ways:
They allow for a narrower bore hole which requires less grout.
The narrower bore holes require less annular space resulting in more efficient drilling.In addition, Centennial Bullet U-Bend fittings allow for the easy insertion of Centennial Cenfuse Geothermal pipe into the bore hole:
Fitting vents allow material to be displaced as the bullet fitting is inserted into the bore hole.
Knockouts are provided for directional/horizontal boring applications.
