Product Questions & Answers (5)

Question by: Ronnie M on Dec 14, 2025, 11:29 AM
got a 3-1/2 inch hose, is this clamp actually sized for that or am i gonna be fighting it
Answer by: Customer Support on Dec 16, 2025, 7:20 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.
Question by: Dustin A on Aug 5, 2025, 11:12 AM
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
Answer by: Customer Support on Aug 7, 2025, 9:33 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.
Question by: Rhonda A on Jul 8, 2025, 6:02 AM
What size is this clamp? Just want to be sure it'll fit my hose.
Answer by: Customer Support on Jul 10, 2025, 8:22 AM
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.
Question by: Lynn B on Dec 10, 2025, 12:49 PM
got a 3-1/2 inch hose, is this clamp gonna fit right or is that 3.50 number something else
Answer by: Customer Support on Dec 11, 2025, 8:03 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.
Question by: Sheila A on May 17, 2025, 4:03 PM
does this clamp lock down without any special tools or do I need a crimper to get it seated right
Answer by: Customer Support on May 18, 2025, 4:04 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.
