Nerrad Jet Swet

[Deleted member 96286]

Just bought the Nerrad Jet Swet kit in 15mm and 22mm. I'm hoping they are as good as they appear on their YouTube video as I intend using them on valve changes on storage tanks and bunging pipes elsewhere temporarily for maintenance. Bunging a freezing cold storage tank in a cold Scottish Winter is not nice and draining down tanks and other low pressure storage vessels is time consuming and these gizmos looked like they'd save a lot of time. Expensive for what they are, but if they are any good, they should pay for themselves.
Any of you lads and lassies got a personal review on these?

I believe you can replace the rubber if it gets damaged ?

 

[Robert Bell]

Do they fit past the burr left by a pipe slice okay?

They do, because it's a Nerrad ratchet type pipe slice that they use on their YouTube video.

That's good to know, cheers. I can get a 3/4 one for imperial pipe if it works as expected.

Massive price that is, I remember when they first came out. They weren’t made by Nerrad and were around £30.00 for the 2.

It was an American bloke that first designed and marketed them. Like most things these days, the bigger more established companies make the inventor an offer that he/she can't refuse and the company buys the rights to them and then sells them under their own name.

I knew they definitely weren’t Nerrad.

My Nerrads are 100% mine, although cold weather and auld age does have a detrimental effect.

I’m surprised if it’s protected under patent etc, it’s a tool that’s been in use for years.

Has anyone actually used one? I’ve looked at them but already have a tool box full of good ideas that in practice I very rarely use.

Nerrads Versa Funnel is a really handy bit of kit though.

Not for me, space is at a premium.

I used it recently to change a 22mm valve on a HWC. Worked a treat but it's way overpriced for what it is.
The bendy Versa Funnel is another item that's been around for years. Garages and automotive services, have been using them for oil and fluid changes, long before it became a plumber's accessory.

I've got the bog Rothenberger pipe freezer on my shopping list. Its 10 times the price but 100 times more useful IMHO.

I suppose we could make something similar.
Basically just a cylindrical piece of rubber expandable on a bolt between two nuts on a long shaft.

Yeah, I'd just had the same thought. Hadn't realised how eye wateringly expensive they were.

I've got some seamless stainless tube at home, going to order some 6mm stud bar and a couple of washers. So long as you used a nylock/thread lock on the inserted end its a winner.

I've got the Co2 Rofrost kit that uses carbon dioxide. Very cheap now to buy and the kits are regularly available on Ebay. The bottles of carbon dioxide are also available on Ebay. I sometimes work in older buildings, where the power has been cut off and where it would be impossible to use an electric freezer. The Rofrost doesn't use electricity, only liquid carbon dioxide and has paid for itself many times over.
As to the washers inside the Jet Swet, an inflatable tube would in my opinion work just as well, if not better, and possibly allow non full bore valves and fittings to be used, which the Jet Swet is incapable of doing.

I used to be able to get liquid nitrogen from work for homers but changed jobs.

How long does the Rofrost take to freeze a 22 or 28 mm pipe? I don't think I'd use it much away from power. The bit Rothy unit will freeze in about 8-10 mins. the nice thing being you can leave it on while your working and it will also defrost for you.

The gas takes about 5 minutes to freeze a 22mm copper pipe and stays frozen for around 5 minutes depending on room temperature, or indefinitely if you keep the gas on. No compounds on the pipe or power is required, just the fitting and the gas. Great piece of kit and uses the same liquid Co2 bottles that pubs use and are readily available from gas bottle retailers.

Hadn't even seen them, looks like a cheaper option. Will they let you use on site? Could see safety people being a bit anal about CO2

Yep, used the kit on site. Safer than the oxy acetylene that the welders use on site. There are as far as I know, no hazards from Co2 in this form as it's stored and used as a liquid, not a gas. Of course ventilation is required and you just open a window. The kit is a fraction of the cost of the big electric kit and a hell of a lot lighter. I store and carry my wee bottle of gas upright on a cheapo sack type trolley I bought in a local hardware shop and it's secured by a padlock and chain. This kit was my first choice as it can be used anywhere as it doesn't need power. I've had mine since 2014. Get yourself a good local gas supplier where you can first buy the bottle and have it refilled as needed. BOC will charge you an annual £80 rental fee on their bottles, so it's best just to buy one.

CO2 is an asphyxiation, I'm not sure how keen schools/hospotals/house builders/companies would be about it being used on their site. As its odourless its a bit of a concern haginv it in the back of a van. I guess you could fit a CO/CO2 meter to solve that. It obviously carries a risk being a compressed gas and cryogenic too.
