PXL25-8 Partex PXL copper tube ring terminal, 25mm², M8 stud, pack 50

Why Choose the Partex PXL25-8 Copper Tube Ring Terminal?

The Partex PXL25-8 copper tube ring terminal is a professional medium-duty, uninsulated electrical crimp lug designed for terminating 25 mm² copper conductors onto M8 studs and bolts. Manufactured from high-conductivity copper with a protective bright electro-tinned finish, this terminal provides a dependable connection for electrical distribution equipment, industrial control panels, machinery and commercial electrical installations.

Part of the Partex PXL copper tube terminal range, the PXL25-8 features a bell-mouth barrel entry to facilitate conductor insertion and an integrated inspection hole that allows installers to verify cable positioning before crimping. Its closed-ring palm provides secure mechanical retention when fitted to a compatible M8 connection point, making it particularly useful for permanent and semi-permanent electrical connections.

Supplied in a convenient pack of 50 terminals, the Partex PXL25-8 is ideal for electrical contractors, industrial panel builders and maintenance engineers carrying out repeated cable terminations. With a 6.8 mm barrel internal diameter, 13.0 mm palm width and 33.0 mm overall length, this compact M8 copper tube lug combines practical installation features with robust construction.

Secure 25 mm² Crimp Connections for M8 Electrical Terminals

The Partex PXL25-8 M8 copper tube terminal provides a practical method of connecting 25 mm² copper conductors to stud-mounted electrical equipment. Its tubular barrel is designed to accommodate a correctly prepared conductor, while the bell-mouth entry helps guide the cable into position. The inspection hole allows the installer to confirm that the conductor has been fully inserted before crimping. When compressed using a suitable crimping tool and die, the barrel forms a secure mechanical and electrical connection with the cable.

For reliable installation, electricians should confirm the conductor cross-sectional area, strand construction and stud compatibility before selecting the terminal. Strip the insulation to the appropriate length without damaging the conductor strands, then crimp using the recommended tool and die combination. After crimping, inspect the connection and secure the ring palm to the M8 stud using the equipment manufacturer's specified tightening method. As the PXL25-8 is uninsulated, suitable sleeving, insulation or protective barriers may be required depending on the installation.
