For Aluminium and Copper Jointing
PLP’s jointing compounds are formulated to improve jointing conductivity and inhibit oxidation and corrosion between jointing contact areas. Jointing compound should always be applied to the contact surfaces of all aluminium to aluminium, aluminium to copper and copper to copper connections prior to compression or bolting.

| Application | Compound |
| For all Bolted Joints | EP Jointseal, EP Uniseal |
| For Copper Conductors in Aluminium Fittings | EP Jointseal |
| For all Non Tension Aluminium Conductors | EP Uniseal |

EP Uniseal consists of a lithium based 180°C stable grease and zinc particles. The base grease prevents water and contaminants interfering with the connection and prevents the formation of surface oxides. The zinc particles work to break down existing oxide on the conducting surfaces when those surfaces are brought together under pressure. EP Uniseal is ideal for aluminium to aluminium and aluminium to copper compression or bolted joints.
EP Joint seal is made up of lithium based 180°C stable grease and titanium oxide. Joint seal is recommended for copper conductors in aluminium fittings and copper to copper connections. EP Joint seal assists the breakdown of contact resistance, fills any voids left after compression and prevents water or contaminants from entering the joint.
EP Unigrip C has a noticeably gritty texture being made up of lithium based 180°C stable grease and aluminium oxide particles. The compound serves as a locking device for aluminium conductor being joined or terminated by compression in full tension situations. The aluminium oxide breaks down surface oxidation, while the base grease prevents water or contaminants from entering the joint.
