SYKRSS4AN Hose Separator Clamp Fuel line Mounting Clamps Aluminum Hose Fitting Adapter for 1/4 Fuel Hose, Oil Line, Brake Line, Water Pipe and Gas Line 4Pcs Blue

I'm not sure if they changed their fitting size or reviews are all off. Because from reviews people say go the next size up so I went with 8AN when my line is 6AN. Well the 8AN which the bag says it is, turns out to be way to large as you can see by the picture.The product itself looks sturdy and well made so I'm not blaming company for the wrong size but more the wrong size because I listened to reviews.

I bought these to separate the -8 hoses on my catch can. I had them zip tied previously and it looked tacky. These look and fit great.

These fit perfect. I actually used them to run 3/8" fuel (AN -6) line and split a rubber line to act as a shock absorber. I am running a supply and return fuel line and keeping them parallel. When I measured the diameter, an AN -8 separator clamp would work perfectly, which these did. You really can go wrong, especially since it's hard to secure BOTH lines on the frame - this makes everything work nicely.

These are a great product, but if you want them for socketless hose, AKA push-lock, AKA twist lok, you will need one size up. I purchased -8AN separators for my fuel lines, but the clamps are WAY too small for -8. These do work on -6AN hose though. I will be purchasing additional -10 clamps for my fuel hose.

I like these pieces, but you have to order the next size up - IE -10 clamps fit my -8 nylon braid hoses perfect, but do not fit regular rubber hoses. WOULD RECOMMEND, just order properly.

Works perfectly on black nylon braded AN-6 hose. Finish is nice and the little cap screw is actually polished stainless steel. A magnet will not stick to screw. Fits loose on high pressure stainless braded line but nothing a wrap or two of black electrical tape wouldn't take up, which you would probably want on that type of hose anyway with this type of clamp to get the fit just right.

I've bought the earl's seperators in the past... they have a beefy body & bigger bolt than these, however they are more than double the price of this product. the hoses I am using these for are not that heavy, so these will do the job just fine, I just wish the mounting bolt was a little bigger, will be replacing with a grade 8 bolt for peace of mind.

Purchased hose "kit" with all AN-10 fittings. Ordered these supplemental pieces by description only (no specification of hose outside diameter_. They are marked AN-10 and they fit the hose suppled with my AN-10 kit. Not sure what all the controversy is about. Perhaps people do not understand how the system work. You do NOT have to order the next size up. If you're got hose that works with AM-10 fittings, these AN-10 separators will work properly on your hoses. <period>

works perfect keeping the hoses in place no vibration

Not 3/8 , a little over 1/2" more like .509
