The
Stäubli PV-MS-MC4-EVO READY spanner set is the genuine manufacturer open-end spanner pair designed specifically for Stäubli's
MC4-Evo ready crimp-free connector range. Supplied as a two-piece plastic set, these spanners handle pre-tightening, loosening, and unlocking of MC4-Evo ready connectors, which use a tool-based crimp-free termination method rather than conventional crimped contacts.

Function
⚠ Not interchangeable with standard MC4 or MC4-Evo 2 spanners
The MC4-Evo ready connector system uses a different spanner profile from both the original MC4 (PV-MS) and MC4-Evo 2 (part of PV-MS-PLS) ranges. Using the wrong spanner set risks damaging the connector housing or failing to properly engage the cap nut. Confirm your connectors are specifically the MC4-Evo ready, crimp-free type before ordering this set.
◆ Crimp-free system, but torque still matters
MC4-Evo ready connectors are crimp-free (no separate crimping tool required for termination), but the cap nut and cable gland still require correct final torque for the connector's rated IP68 seal and mechanical strain relief. This spanner set handles pre-tightening; use alongside Stäubli's PV-WZ-TORQUE-SET for final assembly torque.
ℹ Plastic construction for this connector range
Unlike the metal PV-MS-PLS set used for MC4/MC4-Evo 2, the MC4-Evo ready spanner set is supplied in glass-fibre-reinforced plastic, matching the lighter-duty tooling profile of the crimp-free connector range.
Purpose-Built for MC4-Evo Ready
Machined specifically to the MC4-Evo ready connector cap nut and lock profile, avoiding the fitment issues that can arise from using a standard MC4 or MC4-Evo 2 spanner on this range.
Two-Piece Matched Set
Supplied as a matched pair, covering both halves of the connector pairing so pre-tightening and unlocking can be carried out correctly on both plug and socket sides.
Dual Tightening and Unlocking Function
As with other Stäubli spanner sets, each tool doubles as both a pre-tightening tool for the cap nut and an unlocking tool for releasing the plug-in connection.
Lightweight, Glass-Reinforced Plastic
Fibreglass-reinforced plastic construction keeps the tool light for all-day carry on a tool belt, while remaining robust enough for repeated site use.
Wide Operating Temperature Range
Rated for use across a -30°C to +85°C ambient range, suiting exposed rooftop and ground-mount installation conditions in the UK across all seasons.
Genuine Manufacturer Compatibility
As a genuine Stäubli tool, correct fitment and function on MC4-Evo ready connectors is assured, protecting both installation quality and connector warranty.

Will this spanner set work on standard MC4 or MC4-Evo 2 connectors?
No. This set is machined specifically for the MC4-Evo ready crimp-free connector profile and is not interchangeable with the PV-MS (MC4) or PV-MS-PLS (MC4/MC4-Evo 2) spanner sets.
What does 'crimp-free' mean for MC4-Evo ready connectors?
MC4-Evo ready connectors use a tool-assembled termination method that does not require a separate crimping tool. This spanner set is used for tightening the cap nut and cable gland, and for releasing the plug-in lock, rather than for terminating the conductor itself.
Do I still need a torque tool with this spanner set?
Yes, for final assembly to the correct torque, Stäubli's PV-WZ-TORQUE-SET should be used alongside this spanner set to ensure the cap nut and cable gland reach their specified sealing torque.
Is this spanner set suitable for outdoor use in cold weather?
Yes, it is rated for an ambient temperature range of -30°C to +85°C, suitable for UK rooftop and ground-mount conditions year-round.
Is this a two-piece set or a single tool?
It is supplied as a set of two spanners, allowing both halves of the connector pairing to be handled during assembly and disassembly.
