FUSEAL® is the only thermoplastic chemical waste drainage in the UK, which has flame retardant properties. This provides added security to the end user. The distinctive colour and markings also give a clear identification.

The Fast-LockTM jointing mechanism is unique to Fuseal® and assists in a quick installation, with no grooving required.  With electrofusion jointing technology also as standard, the lightweight data-storing welding machine makes installation hassle-free and easy to manage.

Fuseal® is a full-system solution from "sink to drain" with off-site fabrications ensuring a straightforward installation.  The option of dual-containment provides added security when required.

With so many advantages, Fuseal® is a high-quality chemical drainage system which is difficult to ignore.

Key Applications

Chemical waste containment

Excellent chemical resistance and physical properties ideal for handling corrosive waste mixtures of acids, bases and solvents. Diluted mineral acids and aqueous solutions of acid salts, which are destructive to most metals.

School, college and university laboratories 

Science and education go hand-in-hand. During experiments, lessons and tests, laboratories need to safely discharge hazardous chemicals. With FUSEAL® the corrosive waste is securely drained away. 

Hospitals and the health sector 

The health sector requires a vast array of chemicals to undertake tests and processes. FUSEAL® has been expertly designed to meet these needs. 

Chemical process 

Industrial applications and factories where the processing of chemicals takes place, is another typical application where FUSEAL® can safely evacuate corrosive waste. 


Water treatment, where the monitoring of the quantity, quality, filtering, pH levels, particulate matter, salts, and chlorine levels are all important in delivering clean water across the globe. 

Food and beverage 

In applications where chemicals are required to clean and maintain a high level of hygiene, such as food & beverage, FUSEAL® can securely deal with corrosive waste to help maintain the hygiene levels required. 

One system, many applications

Suitable for use anywhere where mixtures of acids, bases and solvents are conveyed, where stainless steel, cast iron, clay and generic plastic materials fail to stand up to the corrosive nature of certain waste streams. Most major pharmaceutical manufacturing facilities and the top universities worldwide have FUSEAL® currently installed.

Below-ground applications

Whilst being perfect for above-ground systems, the FUSEAL® chemical drainage system is also a safe, secure and cost-effective choice for below-ground applications. Offering all the same benefits, the buried systems are additionally supported with a wide range of fittings, components and accessories that cover all possible configurations with fully bespoke options also readily available.

Fusion and Jointing

An engineer or contractor can combine the benefits of the FUSEAL® electrofusion joint and the mechanical joint in a single system. FUSEAL® can be used in inaccessible areas: The Fast-Lock™ mechanical joint works well under benches, where speed of installation or future disassembly is needed. One lightweight welding machine can do all that is required on-site.

Above-ground Applications

In above ground installations, the pigmentation protects the system from sunlight. FUSEAL® is highly resistant to ultraviolet radiation and is heat-stabilised to provide long life while handling hot reagents.

Fuseal® Case Study | Fast-Lock™ Mechanical Joint PP Corrosive Waste

The Fuseal® Fast-Lock™ Mechanical Joint Polypropylene system from GF Piping Systems is ideal for harsh corrosive waste applications. Fast-Lock™ goes together quickly with a simple socket set or cordless screwdriver. Unlike solvent cement systems, there is no need to wait for cure times before pressure testing or fumes to deal with. If changes in design happen real-time, the system can be reconfigured without having to cut fittings out. This video illustrates an example installation at a laboratory.
