Norma 01266704060-000-0542 Hose Clamps, 50 mm-70 mm x 9 mm W4 (Pack of 10), 2, Pack of 10

I watched a YouTube video where this engineer runs a series of strenuous tests on hardware from different manufacturers. Well, this time around he bought hose clamps from 8 different manufacturers and ran them through pure hell. Every test culminated in the destruction of every single clamp. So who was the winner? Norma was the clear front runner in nearly all of the tests. This is why I bought a large supply of every single size that Norma makes for my automotive shop. Zero failures to date.

High-quality metric hose clamps work great as replacements for the OEM BMW motorcycle air boot clamps, allowing roadside access to throttle bodies without a "special" tool.

Hard to find the narrow width clamps at the hardware store. If you're using these for BMW M3 throttle body boots, use the 50mm-70mm size. They're perfect.

these are premium clamps that don't dig into the hose.

Excellent quality in a hard to find clamp width

Used on a KTM 690 enduro airbox. Exact fit both width and diameter

These are great hose clamps that are narrow and very high-quality!

Should have bought the next size up, which was my fault. But great hoe clamps!
