Butt fusion is the most common fusion methods for HDPE pipe, and the HDPE butt fusion fittings are the most popular used fittings for HDPE piping systems


The main features that HDPE butt fusion fittings are:

※ Reliable jointing

The HDPE pipe & HDPE butt fusion fittings are connected by butt-fusion method of joining. The jointing shall be 100% leak-free when it is properly made, the jointing is as strong as the pipe itself and has the same life expectancy.

※ Wide ranges & specifications available

HDPE butt fusion fittings can be supplied in wide ranges & specifications, which can cover all HDPE pipes. For the big diameter HDPE pipe like dn710-1200mm, fabricated type HDPE butt fusion fittings are the only choice, while HDPE electrofusion fittings are not available for most manufacturers.

※ No coupler need, Lower costs.

When HDPE pipes are connected by butt fusion methods, no any need coupler fittings be requested. By comparison to HDPE electrofusion fittings, HDPE butt fusion fittings are much lower on prices. This greatly reduce the installation costs.

※ Good flexibility

The HDPE pipes be installed by butt fusion method are much more flexible.

※ SDR11 & SDR17 for choice

HDPE butt fusion fittings can be provided in SDR11 & SDR17 with different prices. The customers can always find a correct option according to their pipe.


To achieve the butt fusion, the HDPE butt fusion fittings’ outer diameter shall be exact same to the HDPE pipe. By using a HDPE pipe butt fusion machine to fusion both ends in a certain temperature & time, and then remove the heating plates, tightly bond together the both ends under fixed pressure till it is cool down.


SUNPLAST HDPE butt fusion fittings can be provided in a diameter dn63mm to dn1200mm. The diameter DN63-800mm can be injection moulded in SDR17/SDR13.6 & SDR11, while DN900-1200mm can be provided in FABRICATED TYPE only.
