Merlin Motorsport is celebrating 36 years in motor racing in 2023 and amongst the vast stocks at their Castle Combe circuit-based store is over £150,000 of Samco Sport hoses including various pre-cut lengths of aluminium hose and joiners and they can make up specific lengths and bends for customers.

They carry all the Samco racing parts including elbows, straights, T-pieces etc., Classic, Pro Fuel and Xtreme products. They also keep a large range of Samco car kits.


Common questions they often get asked when it comes to measuring hoses and tubes is what do you actually measure? Do you measure the O.D. (outside diameter) or the I.D. (inside diameter or bore)?

By ‘hoses’ they mean silicone or rubber hoses used for coolant, air, fuel, oil etc. By ‘tubes’ they mean tubes made from aluminium, mild steel, stainless steel etc. to join the hoses together.

They have a very informative feature HOW TO MEASURE HOSE & TUBE
