Hi Oscar - thanks for getting in touch. I found your order and you definitely ordered a 1", part 590306SP. It's possible you just chose the wrong part at the drop down. You can get a return in place at this link:

“Can't say how well the part works. Ordered 28 business days ago over 5 weeks. Had to have the sprinkler fixed in the meantime. Disappointed in the shipping speed, but also that my order wasn't shipped for more than 3 weeks after the order was placed.”
HI Wendy - thanks for your order and our apologies for the delay on the order. The parts were backordered with Hunter at the time of ordering - it looks like the parts were showing out of stock on the website and our system kicked out an email to you notifying of the backorder as well. It did take an ususually long period of time for those to arrive from Hunter.
