Vaillant ecoMAX / ecoTEC Graphite Burner gasket Kit o-rings washers, seals boilers spares

1. Product Overview

Our Sealing Gasket Kit is designed for condensing heat exchangers. It includes O-rings, gaskets, and washers — small components that play a critical role in keeping the entire system sealed, safe, and efficient.

2. Our Key Advantage — We Make Both

The most important difference about our gasket kit?

"We make the sealing gaskets. We also make the heat exchangers."

Both products come from our own factory. This means every gasket in our kit has been designed, made, and tested together with our heat exchanger — not sourced from a third party and simply resold.

3. What Does This Mean for You?

Better Fit — Because We Designed It Together

Our gaskets are not generic parts. They are engineered specifically for our heat exchangers — the dimensions, the compression rate, the material grade — all matched in-house.

Result: No gaps. No leaks. No guesswork.

Fully Validated — Because We Tested It Ourselves

Before any gasket kit leaves our factory, it has already been through real-world testing on our own production line:

Every kit you receive is a proven, validated product — not a theoretical fit from a catalog.

Safer System — Because Every Part Is Under Our Control

Seals are made from Graphite — selected specifically for condensing boiler environments.

Resistant to weakly acidic condensate (pH 3–5) and high-temperature flue gas.

Prevents two critical risks:

· Noxious gas leaks — keeping combustion gases safely inside

· Water leakage — protecting the appliance and surrounding area

More Reliable — Because We Own the Full System

If any issue ever arises, there is only one supplier to call — us. We control every step from material selection to final assembly. You get:

· Faster problem resolution

· Full technical support

· Consistent, traceable quality

4. What's Included in the Kit

· ✅ Flat Gaskets

· ✅ Washers / Sealing Rings

· ✅ Custom configurations available on request

5. Why You Can Buy With Confidence
