Replacement Combustion Chamber Gasket Kit 0020188930 For Vaillant Boilers

Product Overview

What makes our sealing gasket kits more dependable?
"We are the direct factory manufacturer of both products."
From gasket production to heat exchanger manufacturing, all components are developed under one quality control system to ensure stable operation and accurate compatibility.

Our Key Advantage — We Make Both

What makes our sealing gasket kit different?
"We manufacture the sealing gaskets. We also manufacture the condensing heat exchangers."
All components are produced inside our own factory. Every gasket is developed, tested, and matched directly with the heat exchanger system instead of being purchased from outside suppliers and resold.

 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

What's Included in the Kit

·   O-Rings (various sizes)

·   Flat Gaskets

·   Washers / Sealing Rings
