Quarco Fitting Covers: Why Use Them?

Fitting covers protect your connection elements against electrical and environmental risks. Your system lasts longer, work safety improves and maintenance costs fall. Quarco covers provide durable, flexible protection that fits fittings and terminals of different sizes and forms.

Features and Benefits

What fitting covers deliver

Electrical Insulation
- Fully covers metal connection points and keeps conductive surfaces from being exposed.
- Reduces the risk of unwanted contact, short circuits and leakage current at cable lugs, terminals and fitting connections.
- Protects personnel from accidentally touching live parts and minimises the risk of electric shock.
- Prevents arcing and flashover between adjacent connections, and between a connection and the chassis or housing.
- Stops moisture and dirt from forming a conductive bridge, so insulation performance holds up in harsh environments.
- Forms a safe insulating layer in switchboards, battery connections, motor terminals, generators and power distribution systems.
Surface Protection
- Protects the fitting's threads, hex body and connection surfaces against impact, scratches and wear.
- Prevents threads from being crushed or deformed during assembly, transport and storage.
- Keeps dust, dirt and foreign matter out of the connection point.
Corrosion Resistance
- Cuts off contact between moisture, water and humidity and the metal surface, preventing rust and oxidation.
- With no oxidation on contact surfaces, contact resistance does not rise, so there is no heating or energy loss.
- Extends the life of stainless steel, brass and copper connection elements.
Chemical Resistance
- Resists oils, fuels, solvents, battery acid and a range of industrial chemicals.
- Prevents surface damage that chemical interaction could cause.
- Used safely in automotive, hydraulic, pneumatic and chemical plants.
Heat Resistance
- Keeps its form and insulating properties at both high and low temperatures.
- Does not crack or harden under sudden temperature changes.
- Reduces the risk of contact burns at current-carrying connection points that heat up.
Flexible and Durable
- Its flexible material fits the connection snugly and is easy to put on and take off.
- Does not tear or lose its form with repeated use.
- Conical, cylindrical and elongated options fit fittings and terminals of different sizes and types.
