40 Pcs 1/4 ID Spring Band Type Clamps, 6mm Fuel Hose Clamps Fasteners, Black Spring Hose Clip for Fuel Hose Line Water Pipe Air Tube Silicone Hose, Fit 6.5-7.2mm OD Hose

Nice quality clamp but to small for 1/2 i.d. vinyl hose. Will probably use on lawn mowers.

Worked great but had to order 4 different sets to get the right size for my fuel lines my zt lawn mower took the 12mm and my Honda 3 wheeler took the 10mm but bought the 8 and 6 didn’t fit and had to return

I have had no problems so far. The clamps work as advertised. The inside diameter fits around a 1/4" drip line. It holds the line much tighter than without it. I used them to attach drip lines to syringes for a hydraulic line for an underwater robot competition. I would imagine it would work just fine with fuel line as long as the fuel line has an OD no bigger than 1/4". You may have a 1/16" of play but it will be tight.

I bought the 10mm black ones. Out of the bag they measure about 9.9mm-10mm (.39 inches) in their free state. I used pliers to squeeze it as far open as I could 2 or 3 times and it did not break. However, it didn't return to its original size either. It now measures about 10.4mm to 10.7mm (.41 to .42 inches). Fully open is about 12.2mm (.48 inches). I also bought the 8mm (5/16") yellow zinc ones. They measure 7.9mm (.31 inches) give or take in the free state. Fully open is about 9.7mm (.38 inches). Again, the piece I tested did not break. After squeezing it now measures about 8.4mm (.33 inches). I would recommend that you don't squeeze them fully open if you can help it so that they don't stretch as much. I've got some 3/16" I.D. - 5/16" O.D. Oregon brand yellow fuel line. It measures about 7.9mm O.D. (.31 inches). If I use this tube on a barb meant for 3/16" I.D. tubing the 8mm spring clamp will probably be correct. If I stretch this tube over a barb for 1/4" tubing then the 10mm clamp will likely be the one to use.

These clamps work great and are a super value. Be sure to order the size for your application. The ones for small engine fuel filters and shut off valves is 12 mm. They will fit 1/4 inch inside diameter hose. The nominal outside diameter is 1/2 inch or about 12 mm. I will definitely buy these again.

Completely wrong they displayed it for 1/4 due line and it came in and it’s legit for weed whacker fuel line not lawnmower/snowblower fuel line

Poor item description; measure your hose with a metric device and go by the OD. I ordered without reading all the reviews of getting the wrong size. I measure my hose and it came to an OD of 18mm so the 10mm clips were a joke. I should have ordered the 18mm version. The product descriptions should be rewritten and maybe include a warning to measure your hose for your given application.

Great product

good quality

Perfect nice an tight does as it should holds up to the weather

They seem to be good quality but after some research I decided gear clamps and single ear clamps are a better option for long term dependability.

Just fits on a Briggs and Straton gas line.

Bon rapport qualité-prix
