Firegum 150 g exhaust sealant
Product description
If you need a reliable way to seal an exhaust joint, Holts 9236 Firegum is built for the job. This mounting paste helps create a gas tight pipe seal, and it is made to hold up against vibration once fitted. It also hardens from exhaust heat, which can support a more secure connection over time.
Key points

Holts Firegum mounting paste is designed for exhaust system work where a tight, dependable seal matters. The product is intended to create a 100% gas tight pipe seal, helping reduce the chance of leaks at the connection. Vibration resistance is also part of the design, which is useful on roads where engine movement and driving loads can loosen weaker seals. As temperatures build during normal use, the paste hardens from the exhaust heat, supporting a more durable joint finish. 🔧


When you are tackling an exhaust pipe joint, the practical question is whether the material can stay stable under heat and movement. This paste is meant to resist vibration, and it also helps prevent rusting, so you are not just sealing for today, you are looking to protect the joint as it sees regular use. For many DIY and maintenance jobs, that combination of sealing plus heat hardening is what makes a difference. ✅

What’s included
You get a single 150 g tube of Holts 9236 Firegum, a mounting paste for exhaust system sealing. The tube format is convenient for applying a controlled amount to the joint area, rather than dealing with loose material. This is the kind of product you typically keep on hand for exhaust repair and maintenance tasks. 🔩

Who it’s for
It’s a good fit if you are repairing or re-mounting an exhaust system joint and you want a paste that forms a gas tight seal. It also suits people who want material that can stand up to vibration and then harden from the heat of normal exhaust use. You may want to skip it if you are looking for a simple fitting method with no sealing compound involved. It might not be a great match if your project needs different installation methods that do not use mounting paste for exhaust connections.
