Good quality copper/asbestos type washer to fit both inlet and exhaust manifold nuts on Douglas 2 3/4hp models. They should also fit exhaust on EW Models. Price is per bag of 4.
These are copper/absestos type 'crushable' washers to fit both the inlet manifold and exhaust manifold nuts on Douglas 2 3/4hp models. They may also fit 4hp models and the later EW model inlet manifold. If you are nut sure, email for dimension details at sales@racingvincent.co.uk
Note: although traditionally, this type of heat resistent washer is referred to as 'copper/absestos' type, they are actually mineral filled, absestos having been obsolete and dangerous for many years.
These should be replaced every time the inlet or exhaust nuts are untightened, to ensure proper sealing. Price is for a bag of 4 washers.
