PG48 covers 37 mm to 44 mm cable on a 59.3 mm thread, the same band as M63 on a 63 mm thread. Why 3.7 mm decides the panel, and how 14 mm of thread leaves 9.5 mm of usable wall.

The half inch is a nominal pipe size, not the thread. A 1/2 inch NPT gland measures 21.34 mm, needs a 21.5 mm clearance hole or a tapped entry, and gets its cable range from the insert rather than the thread.

IP68 says nothing about depth on its own. How immersion bands, compression set and cable load decide whether a submersible cable gland survives a pump, tank or wet well.

A PG9 cable gland seals 4 mm to 8 mm cable and needs a 15.2 mm hole. The five dimensions, the M16 overlap that fails on the panel, and the two edges where the size is wrong.

A flexible cable gland uses the same elastomer to seal the entry and to take the cable’s movement. That single fact sets two temperature ratings, a life measured in cycles, and an 18 mm ceiling on the spiral range.

PG29 takes an 18 to 25 mm cable through a hole just over 37 mm with a 40 mm spanner. The published dimensions, the PG ladder it sits in, and the three metric threads that clamp the same cable into different holes.
