Thread galling on stainless steel tap

[Bubbles]

Lads,

Some help needed here for the "mechanically-challenged".. Has anyone had issues with thread galling on stainless steel fittings?

I've recently purchased a stainless steel bulkhead and ball-valve tap along with some SS disconnects and I can't get the disconnects into the tap, not even half-way. Would teflon tape be a solution here? Or a food-grade lubricant?

Cheers,
Conor.

In British Standard Pipe Threads (BSP) there are two standards:

Tapered and parrallel

Often quoted as BSPP and BSPT

The males are either P or T the females are always ( IIRC )
BSPP.

So if it only screws in part of the way it may be a T.

Thread galling is usually visible in 1/2" bsp or can be felt with a thumb nail and can be corrected with a small triangular needle file. Female threads tend not to get galled!!
