Fittings
Fittings are used in pipe and plumbing systems to connect straight pipe or tubing sections, to adapt to different sizes or shapes, and for other purposes There are basically two types of copper fittings,compression and capillary A compression fitting comprises of the body an olive and the nut,the nut is threaded onto the body of the fitting and tightened to make a leakproof connection. Fittings are typically made of brass There are two types of capillary - end feed/copper sweat and solder ring/integral ring joint

End feed 90/Elbow
Straight coupler - Compression
Elbow
An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90° or 45° angle, though 22.5° elbows are also made. Most elbows are available in short radius or long radius types.
Coupler
A coupling connects two pipes to each other. If the size of the pipe is not the same , the fitting may be called a reducing coupling or reducer.
Reducer
A reducer allows for a change in pipe size

Olive (can be copper or brass),Insert-Nylon/Metal
Tee
A tee is used to either join or split a flow. Most are tees with the same inlet and outlet sizes, but reducing tees are available as well.

Valves

Ball lever valve (always use full bore)
Gate valve
Ball valves
A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you "see" the valve's position.
Gate valve
A gate valve is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid.

Hole size required
Mechanical flange 65mm
22mm Tank connector 28mm
15mm Tank connector 22mm
You can file or drill out the "stop" on tank connectors which will allow the pipe to pass through
Pockets
You can make a pocket for a thermometer or thermocoupler by filing out the stop on a 15mm tank connector,pass a short piece of 15mm pipe through this and solder on a 15-10mm or 15-8mm reducer then solder in the required length of 8 or 10mm pipe and solder on an end cap
