Frequently asked questions

What is the RTC3629 exhaust nut, and why is it brass?

The RTC3629 is a 5/16" UNF brass nut that secures exhaust components to their mounting studs on Series 1, Series 2, Series 2A, Series 3, and Defender Land Rovers. Brass is used instead of steel because it resists seizing at exhaust temperatures, so the joint can be released cleanly at a later service.

How many exhaust nuts are typically needed for a repair?

Quantity depends on the specific joint. On the 2.25L engine exhaust manifold, typically 4 studs and nuts are used, but mid-pipe and silencer connections vary. Count the studs on your specific joint before ordering to make sure you have enough.

Can a brass exhaust nut be reused, or should it be replaced each time?

Brass exhaust nuts are generally reusable if they come off cleanly and the thread is undamaged. If the nut shows corrosion, deformation, or damaged thread from heat cycling, replace it. Using fresh brass nuts at service is best practice on high-mileage or older Land Rovers.
