Could you clarify what context you're referring to for “PG 13.5”?
It could mean different things, like:

• Cable Gland Size: PG 13.5 is a Panzer-Gewinde (PG) thread size commonly used for cable glands, with a nominal thread size of 20.4 mm and for cables around 6–12 mm in diameter.

• Pipe Fitting / Threading: PG threads are metric-based threads used in electrical conduit and fittings.

• Other context: A product code, rating, or measurement.
