Hammond 1427BCGM12 M12x1.5 Nickel Plated Brass Cordgrip, 3-7 mm Cable

The 1427BCGM12 is a liquid-tight cordgrip (cable gland) made from nickel plated brass with a metric M12x1.5 thread, used where cable enters or leaves an enclosure. It is built for electricians, panel builders and OEM engineers who need a sealed, strain-relieved cable entry. As the smallest metric size in the series, it is meant for thin cables in the 3 to 7 mm range entering an M12x1.5 threaded or 12 mm clearance hole.

An NBR (nitrile rubber) seal and a large opening let the gland accept a wide range of cable diameters. Its strain relief elements tighten in a circular sequence on the sealing ring, gripping the cable without twisting or damaging it. A locknut and an EPDM o-ring are included. The series advises choosing the cordgrip with the smallest maximum diameter that will fit your cable.

Dimensions for this size:

• Thread size (D): M12x1.5
• Mounting hole diameter: 0.47 in (12 mm)
• Wire diameter: 0.12 in (3 mm) min to 0.28 in (7 mm) max
• Outer length (L): 0.75 in (19 mm); inner thread length (T): 0.28 in (7 mm)
• Suggested torque (M12): sealing nut 1-2 N-m, locknut 2.5-3.5 N-m

The part drawing lists a 6.5 mm maximum wire diameter and 6.5 mm inner length, while the series ordering table lists 7 mm for both; confirm against your cable before ordering if you are near the upper limit.

The 1427BCGM12 is designed to meet NEMA Type 4, 4X, 6, 6P, 12 and 13 with protection to IP68, and is UL listed. Working temperature is -40C to +100C, with temporary heat resistance up to 120C. It is RoHS and REACH compliant and ships in a bag at 0.03 lbs (0.01 kg). The torque values are a guide; actual values can vary with the application.
