The 1427NCGPG9LB is the extra-long black PG9 liquid-tight nylon cordgrip. It keeps the same 4–8 mm cable range, 15 mm mounting hole and 22 mm outer length as the standard PG9, but its inner thread length (T) is extended to 0.59 in (15 mm) from 8 mm. It is used where cable enters or leaves an enclosure.

The black (RAL 9005) nylon body houses an NBR (nitrile rubber) seal behind a large opening that accepts a wide range of cable diameters. The strain relief elements tighten in a circular sequence on the sealing ring for strain relief without twisting or damaging the cable. A nylon locknut and EPDM o-ring are included.

Key dimensions: thread size PG9, mounting hole 0.59 in (15 mm), wire diameter 0.16 in (4 mm) to 0.31 in (8 mm), outer length (L) 0.87 in (22 mm), inner thread length (T) 0.59 in (15 mm). Guide torque for PG9 is 1–2 N-m on the sealing nut and 1.2–1.8 N-m on the locknut; actual values can vary depending on the application.

The 1427NCGPG9LB provides IP68 protection, is designed to meet NEMA Type 4, 4X, 6, 6P, 12 and 13, is UL listed with a UL94 V-2 flammability rating, and is RoHS and REACH compliant.
