Plumbing fittings
Brass, PPR and press fittings for a system — not generic hose fittings.
This is the home of plumbing fittings: elbows, tees, sockets for water and heating pipe. Generic hose fittings for the workshop live under Consumables → Fittings. Do not mix them.
Match system and diameter to the pipe. Valves sit next door.
