I am puzzeld a bit with parallel and taper threads.
I understand if I have say a 1/2" bsp parallel female and a 1/2" bsp parallel male, then I will need a washer of some type on a seat to effect a seal.
If I have a 1/2" bsp taper female and a 1/2" bsp taper male, then with some thread tape I should be able to get a good seal, I assume.
So where does say a 1/2" bsp parallel female and a 1/2" bsp taper male fit into the scheme of things? Does it mean the taper will fit further into the fitting before giving a seal?
Are there advantages or disadvatages in mixing tapers and parallels?
I ask this because I was looking at a catalogue of parts and for a gas wall connector (leading to a 1/2" bsp taper male cooker bayonet outlet) available as 1/2" bsp female parallel and taper, it states that "British Gas specify parallel"
