PLAIN-END HDP PIPING SYSTEM
The Lede HDP series of piping components are designed to provide a fast and easy way to mechanically join HDP (high density polyethylene/polybutylene) pipe.
This method eliminates the need for costly heat fusion equipment, solvent joining and or complicated adapters.
Lede HDP piping components are rated to the same
MODEL HDP COUPLING
The Lede Model HDP couplings feature four bolt
housings and a series of sharply machined teeth which positively grip the pipe as the coupling housing is tightened. The result is a leak-tight joint that is as strong or stronger than the pipe itself. It also features a contoured housing with integral ramps along the outside diameter to
help the coupling slide over most obstacles during the relocaton of pipe runs.
HOUSING MOUNTING: Place the housings over gasket and insert bolts. Then apply nuts finger tight.
MARKING: Use a marking pen or other marking tool
and measuring tape to place marks on each pipe end, 1’’ from each end.
GASKET MOUNTING: Place a gasket over the pipe ends and center the gasket in between the mark*. The pipe ends should always be buƩed
against each other.
NUT TIGHTENING: Tighten the nuts alternatively unityl the housing bolt pads meet metal to metal.
These components are designed to join HDP pipe
and fiƫngs conforming to ASTM D2447, D3000,
D3035 or F-714, at ambient temperatures with wall
thicknesses from SDR 32.5 pressure as that of the HDP pipe they are used in conjunction with.
Note: The Lede HDP couplings are not
intended for use on PVC or other materials.
* Lede recommends the use of a silicone based lubricant for use with the HDP series.
