If you’re tired of screwing and unscrewing hot, slippery hoses in the middle of a brew day, Camlock fittings (or cam‑lever couplings) are about to change your life.
Extremely popular in both home and professional brewing, they let you connect and disconnect your transfer hoses in a quarter of a second, with one hand and with perfect leak‑free sealing.
Designed to withstand high pressure and high temperatures, they are the undisputed kings of the “hot side” (mash tun, boil kettle, pump and chiller). Follow our guide to choose the right fitting for your setup!
1. How does a Camlock fitting work?
The Camlock principle relies on two complementary physical elements that lock together without any threading:
- The Male part (the Adapter or “Plug”): A smooth insert with a groove running around its outer contour.
- The Female part (the Coupler): A socket equipped with a flat sealing gasket at the bottom and two side levers (the “cams”).
The motion is incredibly simple: you insert the male part into the female part, then fold both levers of the female part downward. As they pivot, the levers engage into the groove of the male part, pushing it firmly against the internal sealing gasket. It’s locked, airtight and ultra‑secure!
2. The Camlock dictionary: Understanding Types (A, B, C, D, E, F)
This is usually where things get tricky for brewers. Camlock fittings are designated by letters from A to F. Each letter corresponds to a precise combination of the fitting’s gender (male or female) and its connection end (male thread, female thread, or barbed hose tail).
To make things easier, we can divide them into two families:
Male ends (Adapters)
- Type A: Male Camlock with a female thread (usually 1/2" or 1" BSP). Ideal for screwing onto the male threaded outlet of a kettle valve.
- Type F: Male Camlock with a male thread (usually 1/2" BSP). Perfect for screwing into the female threaded inlet/outlet of a transfer pump.
- Type E: Male Camlock with a barbed hose tail. Designed to be inserted and clamped directly inside a flexible hose using a hose clamp.
Female couplers (with locking levers)
- Type D: Female coupler with a female thread (usually 1/2" BSP).
- Type B: Female coupler with a male thread (usually 1/2" BSP).
- Type C: Female coupler with a barbed hose tail. This is the most popular fitting for the ends of your mobile transfer hoses!
3. Visual Camlock compatibility chart
To make sure you never order the wrong part again, here is a summary of the configurations:
| Model | Camlock Gender | Opposite Connection Type | Typical Brewing Use |
|---|---|---|---|
| Type A | Male | Female BSP Thread | Screws onto the male outlet of a kettle valve. |
| Type F | Male | Male BSP Thread | Screws into the body of a pump or filter (female thread). |
| Type E | Male | Barbed Hose Tail | Clamps onto the end of a silicone or EPDM hose. |
| Type C | Female (levered) | Barbed Hose Tail | The must‑have fitting for the ends of your transfer hoses. |
| Type D | Female (levered) | Female BSP Thread | Adds cam‑levers to a male threaded fitting. |
| Type B | Female (levered) | Male BSP Thread | Connects cam‑levers directly into a female thread. |
Rolling Beers Team Tips
The standard setup to get started smoothly: If you want to equip your hot‑side transfer lines without overthinking it, here’s the most logical and economical configuration used by most brewers:
1. Screw a Camlock Type A (male) onto your mash or boil kettle valve.
2. Attach a Camlock Type C (female) to each end of your silicone hoses.
This way, you only have fixed male ends on your kettles (no bulky levers sticking out of your valves) and lightweight female couplers at the ends of your mobile hoses. It’s clean, efficient and ergonomically perfect!
