Tightening Wrench 75-110mm

Tightening Wrench 75-110mm (Reference: 51775110) - This specialized Multitanks tool is designed to facilitate the assembly and disassembly of all your compression fittings and PVC valves with large diameters. Made from high-resistance plastic, this wrench guarantees precise tightening while preserving the integrity of your professional and domestic hydraulic installations.

Applications and use cases

This tightening wrench is the essential tool for all professionals and individuals working on large diameter hydraulic installations. It excels in pool circuit assembly, particularly for filtration fittings, circulation pumps and water treatment systems. Automatic irrigation installers use it daily to assemble main networks feeding irrigation sectors.

In industrial environments, it finds its place in process circuit assembly, water treatment stations and distribution networks. Its compatibility with PVC valves from 75 to 110mm makes it a versatile tool for maintaining existing installations and creating new circuits. Communities adopt it for maintaining irrigation networks for green spaces and sports fields.

Technical specifications and design

Made from high-performance plastic, this wrench resists significant mechanical stress while avoiding corrosion. Its expanded design precisely covers the 75 to 110mm diameter range, adapting to European PVC fitting standards. The profiled jaws perfectly match the shape of compression fitting nuts, uniformly distributing tightening force.

The selected plastic material presents excellent chemical resistance to commonly used water treatment products (chlorine, pH-, pH+). Its reduced weight compared to metal wrenches decreases fatigue during prolonged interventions. Edges are rounded to avoid injuries and allow secure handling even with protective gloves.

Installation and practical use

Using this wrench requires precise positioning on the flats or bearing surfaces of fittings. Place the jaws perpendicular to the pipe axis to avoid slipping. Apply gradual and controlled rotation, alternating contact points if necessary for uniform tightening.

For disassembly, respect the reverse rotation direction while firmly holding the opposite fitting. In case of seized fitting, use a PVC-compatible penetrating oil and wait a few minutes before the maneuver. Cleaning after use is simply done with soapy water, avoiding aggressive solvents that could alter plastic properties.

Store the tool in a dry place, away from extreme temperatures. Regularly check the condition of jaws and replace the wrench in case of excessive wear or visible cracking.

Expert advice and product synergies

This 75-110mm wrench pairs perfectly with our compression fitting range and Multitanks PVC valves. For a complete installation, combine it with smaller diameter wrenches (50-75mm) available in our catalog. This combination allows you to cover all diameters encountered on your job sites.

Professional tip: mark the initial position before disassembly to facilitate reassembly. Always use Teflon tape or sealant paste on threads when reassembling fittings. For temporary or seasonal installations, plan moderate tightening torque to facilitate future interventions.

Complete your toolset with our specialized penetrating oils and lubricants for PVC fittings. In chlorinated environments, regularly rinse the wrench to preserve its mechanical properties. Always keep a spare wrench in your intervention kit to handle emergencies.
