PFAS Regulations: A New Chapter for Seal Manufacturers

Global regulations around PFAS are changing.  PFAS materials have long been favoured for their durability, thermal stability, low friction, and chemical resistance, making them ideal for demanding sealing applications. Now, however, concerns over the environmental and health impacts of these forever chemicals are mounting, and pushing legislation forward, fast.  

With bans anticipated as early as 2026 in the EU and similar movements underway in the US, Canada, and Australia, the seal industry is feeling the pressure. Exemptions may still apply for critical applications, but it’s becoming clear that it’s time to plan for PFAS-free sealing solutions.  

The main problem is that it’s not as simple as a like-for-like material swap. Each material has a unique set of properties, which potentially means big changes. Switching away from PFAS might not just impact the seal material, but the entire system – from performance and reliability to compliance.  

That’s where Clifford Springs comes in. 

We work closely with leading seal manufacturers around the world, and we’re actively involved in technical groups exploring this issue. We understand the pressures you face. And we know that energising springs will become even more critical as sealing systems evolve.  

The spring is the constant force behind the seal – literally. But when jacket materials change – becoming softer, more elastic, or less chemically stable – the load profile required from the spring changes too. Springs may need to compensate for increased wear, pressure cycling, or thermal expansion. Design becomes more bespoke, more precise, and more integral to system success.  

At Clifford Springs, we bring decades of experience in bespoke spring design for harsh environments. From stainless steel to exotic alloys and PEEK®, we understand how spring behaviour must adapt as sealing materials change.  

If you’re exploring PFAS alternatives, our advice is simple: 

• Start early. Give yourself time to explore and prototype.
• Test together. We’re ready to co-develop and trial spring designs with you.
• Stay in touch. Regulations are evolving. Communication helps everyone stay ahead.

PFAS may be on the way out – but energising springs are more vital than ever. Let’s work together to keep your sealing systems performing at their best.
