+KiloWolf - Thanks for the question! We spoke with an HDPE product expert from Centennial Plastics to get you a thorough answer: The HDPE product used for residential/light commercial turf irrigation systems is not a fuseable product. This pipe is made to Standard Inside Dimension Ratio (SIDR) meaning the dimension of the pipe is controlled to a consistent inside diameter for use primarily with plastic or metallic insert fittings. This product is primarily offered with a thinner wall thickness and a maximum pressure rating of 80-250 PSI in diameters of 1/2"-2", with 80-100 in diameters of 3/4"-1 1/4" being the most common. Fuseable HDPE pipe products are made to Standard Dimension Ratio (SDR, DR) meaning the dimension of the pipe is controlled to a consistent outside diameter for use with butt-fusion, socket fusion or compression type fittings. Fusion of SIDR pipe products is not recommended by manufacturers as the outside diameter, which is crucial to lining up the pipe for the fusion process is not controlled and can have variances as only the wall thickness and inside diameter are controlled in the manufacturing process. There are also no SIDR fittings produced for fusing of this type of HDPE pipe for the same reasons.
Thank you for the well thought out answer and info in the post. I was simply wondering as I am a HDPE Fusion tech and I had never seen those types of fittings.

Can you provide any feedback on the blazing fast fittings? I have used the saddles and love them but have never used the other fittings. Thanks!
Why are you guys using fittings for the HDPE and not fusing it?
