WRAS APPROVED LEAK SEALING
At Seal Team Systems, we specialise in WRAS approved injectable leak sealing and injection sealant services that keep your systems running with no need for shutdown. Whether it’s a live steam, chemical, or water leak, our expert team can seal leaks on-site, 24/7, across the UK.
We’ve been sealing live leaks across the UK since 2005, including high pressure steam mains, boiler feed systems, acetone and cyanide lines, and more, without disrupting production. Our professional solutions are suitable for concrete structures, pipework, masonry walls, and tunnels, giving long-term protection against moisture, wear, and tear. For more information or to speak to our experienced team, contact us today.
Using a specially developed polyurethane based compound that meets DWI standards, we inject the sealant directly into failed joints, flanges, valve bonnets, or gland packings, offering a fast, safe, and high performance repair. Our materials combine PTFE, treated fillers, and lubricants for excellent adhesion and durable performance, even in high pressure environments and hard-to-reach areas.

Seal Any Leak With PTFE Injectable Leak Sealing
Polytetrafluoroethylene (PTFE) is an essential material used for injectable leak sealing and injection sealant applications. Small cracks or voids can often be sealed with silicone paste or epoxy putty, but for high-pressure environments or exposure to chemicals, more substantial sealants and advanced techniques are required.
One key advantage of using an injectable sealant like PTFE is that it can seal gland packings, construction joints, valve bonnets and flange joints, with no shutdowns necessary. It is generally applied to the outer rings of pipe joints, filling any voids and forming a flexible surface connection. This makes it an ideal solution for sealing pipework, concrete structures, and masonry walls in high-pressure and chemical environments.
PTFE’s ability as a leak sealer is exceptional. With this polyurethane based sealant, there’s no need to push coolant or flush water through pipelines once inserted. The compound’s low viscosity and very low viscosity forms enable it to fill micro-voids, create a durable seal, and perform reliably under weight, movement, and extreme pressure. PTFE also cures quickly, resists UV light, and offers strong protection against moisture, water penetrations, and chemical wear, making it a trusted choice for critical structures.
The Benefits Of Sealing Leaks With Injectable Sealants
Leak-Free Main Lines
Our injectable sealants are supplied and ready for professional application. We ensure your mains line remains leak-free. This maintains system efficiency, reduces risk, and protects your site from water penetrations and costly downtime.
Easy Installation
PTFE is straightforward to install and is applied quickly by our experts. Its low viscosity formula allows it to penetrate cracks, expansion joints, and voids with minimal effort, making it an effective solution for complex applications.
Extended Lifespan
Using PTFE and other polyurethane-based sealants can significantly extend the life of your equipment. They reduce wear, tear, and environmental damage, keeping your systems durable, flexible, and performing at a high standard for longer.
Minimal Downtime
PTFE reduces the need for offline repairs, meaning less downtime and less interruption to production. It can seal water leaks, chemical leaks, and other failures live on-site, keeping your operations running free from disruption.
What Is Polytetrafluoroethylene (PTFE)?
PTFE is a high performance material within the fluoropolymer family, composed of carbon and fluorine atoms. Known for its versatility, it’s widely used across industrial applications and high pressure environments where chemicals, pressure, and movement are constant.
Its properties include outstanding chemical resistance, excellent adhesion, resistance to UV light, and the ability to cure quickly in wet or dry conditions. PTFE is suitable for construction joints, concrete surfaces, and pipework, providing durable protection against water, moisture, and wear.
It remains flexible, maintains its form, and is proven to perform in tunnels, dams, and concrete structures throughout the UK. These features make PTFE an ideal sealant for a wide range of applications, from heavy-duty industrial sites to commercial structures that require WRAS compliance and reliable curing.
What Are Popular Applications With PTFE?
PTFE is your ideal solution if you are looking for a material with an incredibly high melting temperature and very low viscosity. Our team has been using this injectable sealant for many years across a diverse range of applications, including including those with very low viscosity.
PTFE can be applied for sintering, compression moulding, hot stamping, or full extrusion of products on specialist machinery. It can also form around wire insulations, tapes, and tubes, creating a strong surface connection. The compound’s durable properties and quick-curing form make it a reliable choice for construction joints, masonry walls, and overhead elements. It is compatible with all common materials, including metallic and concrete structures.
The range of properties that PTFE can provide you with depends on the different processing methods you follow, such as the polymer particle size, the temperature at which sintering occurs, and the pressure. It easily handles movement, weight, and pressure while maintaining its durable form. The range of benefits and advantages depends on the temperature, pressure, and curing conditions during production.
If PTFE is not suitable, our team can recommend alternative sealants from our WRAS-approved range, ensuring you always receive the best professional solution for your site.
