Called them up, and they didn't offer me the bits that you showed on your HF5 install. Instead they offered me some different size T's, and reducer stem. Came to £18,something. That's too much for a couple of connectors. I found some of them on eBay.us. Still looking though. The JG offerings here in the UK is pretty appalling. The actual John Guest brochure has got so much more stuff, you can barely buy half of it here in the UK.
