About this accessory
This John Guest fitting connects 3/8″ tube to a 7/16″ NPT female thread and is made in grey acetal. It’s part of the BM10 kit, so it’s the correct piece for joining filtered-water tubing to a 7/16″ NPT threaded component in that system.
John Guest push-fit fittings seal quickly without tools and hold securely under line pressure, which is why they’re trusted for water filtration plumbing. Use this one to make a tidy, reliable tube-to-thread connection.

Before you buy
Built for 58 mm portafilters — the size used by essentially every prosumer machine we sell, including Bezzera, ECM, Lelit, Profitec, Quick Mill and Rocket. If you're on a 51 mm or 54 mm machine, talk to us first.
Tell us the machine you own and we'll confirm the fit before you order. It takes one phone call and saves a return. Call 1300 551 626 →
Dispatched from our Brisbane warehouse, usually within 1–2 business days. Pickup from the Woolloongabba showroom is available if you'd rather collect.

Why buy it here
We don't stock accessories because a distributor offered them. Our technicians use this gear on the bench every day — so if it's here, it's because it holds up and it actually fits the machines we sell.
Goes well with
The grinder matters as much as the machine — here's what we'd pair with it.
