Connection Strength: Integral Fittings are made from one solid piece of metal providing more strength at the connection where it’s needed most.

Better Flow Geometry: The leading chamfers at the bore of DEENPU Integral Fittings creates less turbulence therefore reducing erosion.

Larger Wall Thickness: Our Integral Fittings have a larger wall thickness at the connection to allow the pipe a longer service life.

Replaceable Wingnuts: With a removable retainer ring, the wingnuts on DEENPU Integral Fittings can be replaced when necessary to allow continued service of the pup joint.
