HusqvarnaPart Number 577079301 Middle Tube

I lost the original extensions for my backpack leaf blower, Husqvarna 130BT. This replacement tube fit perfectly and was very easy to install. If you have a 130BT rest assured, this will fit.

It fits tightly on my 150BT. Cheaper, thinner plastic than OEM tubing that came with the blower, but works fine.

Male end is a little loose but locks, female end is tight.

This Husqvarna OEM extension fits good, and my wife likes it―sez I'm doing a better job blowing the leaves around. Really, I didn't even think she noticed. You know, things around the house just get done by themselves. 😉

There is definitely some confusion out there as to what fits what so I figured I'd buy it and return if it didn't fit. Well I can report that it's too small for the 360BT, and nowhere near the same quality of plastic used. Maybe Husqvarna uses cheaper materials for their smaller units but there is definitely a stark contrast in quality.

My husband needed just a little bit more on the leaf blower tube and this worked perfect! Great price also!

The piece does fit onto the original leaf blower, but does not fit tight. I have air coming out from between the sections. Not much, but there is definitely air escaping. When using the blower I can feel the pieces rattling. I will probably duct tape the connections to stop the rattling and air escaping.

I guess Husqvarna thinks Americans are 5 feet or less tall as the supplied tubes just are too short. At 6'4" tall, I added one tube last year which helped a lot and then this one and it's just right for me now, getting the air blast down closer to the ground where it will do a much better job including moving those @#$% millions of acorns
