Anyone ever cut silicon hose

[funkyboogalooo]

Now this is a bit of a wacky question but has anyone ever cut silicon hose? I need to cut a piece but have no room at all for mistakes so need to make sure I cut it with the right thing. If i f**k it up im knackered until I can get another piece late next week. Am I best off with a stanley knife or hacksaw?

Hacksaw, use a jubilee clip as a guide.

stanley knife, have replaced loads of the 4mm vacuum pipes on the Saab, just slices straight through

[R5GTTgaz]

Oh, I was thinking large diameter stuff.

If its 4mm just get the scissors out man ffs

Butchered my coolant hoses with tin snips, but 4mm would be fine with scissors. Just stick a marker on it and cut a little above it, can always trim down if needed

Got on OK with the jubilee clip and a stanley knife when I did mine. The one with the snap off bits where you can extend it all the way.

I bought some of these for cutting up plastic conduit.



They are also perfect for cutting up silicone hose up to about 32mm plus you get a perfectly square cut.

Fit jubilee clip to required length and stick mastic tap along the edge.

Remove the clip then cut along the edge of the tape with either blade or very sharp scissors (needs to be good 'n' sharp!)

I always found that a hacksaw tends to fray the inner web of the hose.

my turbo to IC hose split the other week about 1cm from the end - i tried a hacksaw and and as Dave says, it just teared the hose, catching on the internal web. I swapped over to a stanley knife and it was much cleaner.

Good idea to use a jubilee clip as a guide!

Its 51mm so a fair diameter. I was thinking of seeing if I could get some plastic waste pipe of roughly the same dia as the ID of the silicon to make it more rigid to cut. maybe hacksaw will be best. I also have to make lots of cuts. I need to cut 1 length into 8 pieces

How sharp are your kitchen knives?

[r1ot]

you'll get a better cut with a sharp knife. once you've pushed the blade through the hose the cut will be very easy just use a jubilee clip or large tyrap to keep the cut square a hacksaw will give a really rough cut.

Ive also cut silicone before and a hacksaw will be awfull.

If its not too thick a brand new stanley knife will be the best bet.

I was only cutting 20mm stuff with 3mm wall so I used a scalpel.

I like the idea of using a tie wrap to keep the cut straight, good thinking r1ot

I have trimmed 'Samco' silicone hoses with a stanley knife, no problems....

If you're cutting a large diameter silicone hose, to get a great finish you can use the following technique:

You will need: T bolt hose clamp to suit the size of hose, A spanner for the clamp and a Stanley knife with a brand new blade.

1. Mark the hose where you want to cut with a permanent marker
2. Line up the t bolt clamp, tighten and secure.
3. Keeping your fingers away, slowly use the edge of the clamp as a cutting guide. Cut along until you reach the bridge of the clamp.
4. When you reach the bridge of the clamp, you will loose that line. Rotate and readjust the clamp to get that straight line
5. Cut some more until the entire diameter is cut
6. Remove the clamp and admire your job.

I’m sure he managed to sort it in the last 10 years.
