Product Questions & Answers

got a 3-1/2 inch hose, is this clamp actually sized for that or am i gonna be fighting it
Question by: Ronnie M on Dec 14, 2025, 11:29 AM
With a 3.50 inch inside diameter, it lines up with a 3-1/2 inch ID size. The band is 0.75 inch wide and 0.030 inch thick, so you are matching on the clamp ID and getting that specific band size.

does this clamp actually lock without needing any tools or hammering? seen some clamps that say that but you still end up wrestling with em
Question by: Dustin A on Aug 5, 2025, 11:12 AM
Locks into place with one lever movement, no hammering or crimping needed. The preformed band seats itself around the hose, and the locking mechanism secures it in a single motion. That's consistent with how the whole JS-type line works, so you're not fighting it during installation.

What size is this clamp? Just want to be sure it'll fit my hose.

It's made to fit a 3.5 inch inner diameter hose. The clamp itself is 0.75 inches wide and 0.030 inches thick.

got a 3-1/2 inch hose, is this clamp gonna fit right or is that 3.50 number something else
Question by: Lynn B on Dec 10, 2025, 12:49 PM
Fit comes down to the clamp I D. On this one the inner diameter is 3.50 inches, so it matches a 3.50 inch clamping diameter. It also has a uniform, gap free inside diameter that gives you a smooth clamping surface to help prevent leak paths.

does this clamp lock down without any special tools or do I need a crimper to get it seated right
Question by: Sheila A on May 17, 2025, 4:03 PM
No crimping or hammering needed. The JS type design locks automatically with a single lever movement, so you can get a secure fit without any extra equipment. That makes it a lot easier to work with, especially on assemblies where you're dealing with tight access or repetitive installs.
