Endless Band Hose Clamp with Buckle - 5 mm wide.

Again one of those items that allows you to put the finishing touches on a restoration!

This is the famous "endless band hose clamp with buckle" that was used throughout the 1950's, 1960's and 1970's in the car industry.

Unfortunately, these band clamps are only suitable for one-time use and are discarded after removing them.

Over the years, these clamps have become harder and harder to find but we managed to find a source!

We are selling these in sets.

Such a set consist of the following:

• Approximately 100 cm Zinc-plated band, 5 millimeters wide
• 3 buckles

This way, you have roughly a foot (or 33 cm) of band per clamp / buckle which is more than enough for regular applications.

Thanks to the generous length of band, there is virtually no limit to the diameter or circumference of the clamp that you wish to apply although these were usually applied to small diameter fuel lines.

Please note that this style of clamping is NOT suitable for steel-braided lines.

Gunson Car Balancer.

Internal combustion engines use a mixture of air and petrol to generate their power.

The performance therefore is influenced by the air flowing into it and the petrol that is metered out by the carburettor.

Unless the air flow in Twin or Multiple carburettors is correctly set, the correct mixture adjustment is unlikely to be achieved and this is the simplest tool to achieve that.

Suitable for use on SU, Solex, Auto-Lite (Fomoco), Stromberg, Weber and Zenith and can be adjusted to fit most carburettors including sidedraft, downdraft with air intakes (Venturi) from 25 mm to 67 mm (1”-2”) diameter

• Easy read scale indicates the air flow and allows adjustment to optimum efficiency
• Provides smoother and better acceleration
• Carbalancer can be adjusted to fit most carburettors
• Easy to follow instructions
