Easy two-step assembly
After having lubricated the O-rings, the Supa Lock™ spigot end is pushed into the Supa Lock™ socket end, the safety retainer is clicked on.
Self-locking safety retainer
Supa Lock™ is designed as a tensile joint and withstands pressures up to PN 16 x 1.5. The safety retainer is designed with an edge, which makes it self-locking whenever there is pressure in the pipeline. Therefore, no accidental disassembly can take place. The safety retainer has two finger knobs for easy assembly and disassembly.
Joints with heavy duty O-rings provide extra safety
All Supa Lock™ joints are designed with heavy duty O-rings to secure the joint against leaking. The large O-rings provide extra safety when taking into account that a minor permanent deformation of the O-rings is to be expected over the lifetime of the product. Also, when the joint is exposed to bending as a result of ground movements, the large O-rings provide maximum safety.
No rotation of valves and connectors
Free rotation is restricted on the valves and the threaded connectors used for drilling machines to enable effective drilling. Small cast notches placed on the outer rim of the socket end and on the inner rim of the spigot end interlock and prevent rotation.
360° rotation of the fittings gives maximum flexibility
The design allows for a 360° rotation of the fittings, which is a unique feature only offered by the Supa Lock™ system. The free rotation of the joint allows the installer to direct the service pipe outlet in any direction from the main pipe, thus avoiding collision with other pipes or obstacles in the trench.
