Don't get Hosed! Use an Engineered Solution for Vacuum!

[@char.s1ksmashing444]

Here it the thing tho you usually only can pull thru a 1/4 " port unless your at the rack and you have access to 3/8 angle valve. They don't speed up the evac that much unless you have that 3/8 access

[@EdwardChuck-s3s]

May I know how to use this set on the package unit since the package unit can't pull the core out.

[@coldfinger459sub0]

You made an excellent video so now I could stop trying to explain to every technician how vacuum works and restrictions just save this video to favorites and keep passing it along with all your other videos.

[@UlisesPalacios]

Great Video Jim

[@manismello]

Very nice Video, Jim. Easily understood, good instruction.

[@jessevasquez8323]

Looks like a field connection from the true blue 3/4'' to 1/4'' inch with that butterfly tightener does is actually come from the factory from 3/4'' to 1/4''.

[@Skunkhunt_42]

Is the Blue hose made of a material that has negligable offgassing at sub 100micron? The material be more hydrophobic too?

[@Mikecianfrocco]

Cool info Jim!

[@fieldpiecenorthgreece]

Best video fore vacumm ever!!! Great job!!!! Thank you

[@mss3834]

I bought all this but don’t use it. By the time I hook it all up, I can hook up my field piece manifold with 3/8 hose and pull vacuum in about the same time. Yes this is faster. But I have to use a micron gauge and more fittings. I don’t deny an advantage I just don’t see it when I have to carry more stuff up a 3 story apartment roof and hook up more stuff. I save 3 minutes but spend 10 making more trips up and down the ladddr etc.

[@Automotive_Solutions]

Thanks. Great explanation. Looks like another purchase to add to my wish list. 😁

[@joeoehm4341]

I'm new in the HVAC-field and I'm from Germany. I like the big diameter of the hose. We have always 5/16" SAE connections at the R410a and R32 heatpumps. Can I use the Kit also for 5/16" connections? Is there an adpater included? Maybe it`s a stupid question, but I'm new in this field.

[@ChrisHVAC]

Good stuff Jim!

[@jrm163]

Good explanation! But I think the 1/4 hose is clogged or blocked. There’s no hissing sound at all!

[@MrBen527]

Yeah, and there is nothing wrong with using a 1/4 inch setup like everyone has been doing forever. If a larger system takes 9.5 minutes to pump down or 10 who cares. It's not worth the added cost and lugging around those smurf hoses.

[@trevmint5615]

How long is the blue hose? It looks too short leaving you cramped

[@DJV94022]

They have a 1.5 meter option and a 1 meter option which everyone says to get the 1.5 kit which is called "XL" ..but the closer a dang vacuum pump is to a unit the better it really is

[@trevmint5615]

@@DJV94022 i bought the xl. It's plenty fast for now.

[@OnePointLander]

Great video. Imo, if you are coming from 1/4 hoses, then jump to the trublu. If you already have the Appion 1/2 hoses its not worth it to save a few mins.

[@vw_mods_4711]

Every little helps, I have a 1/2” Appion and 1/2” yellow jacket. will make a massive difference for us automotive guys that do a proper job on the system! actually removing moisture and tracking it on the app with a micron gauge. You 1/2 hour vac & gas guys with 1/4” hoses and analog gauges wouldn’t notice the difference 😂 but the 1/2” to 3/8” fittings will make the most of the pump and gauges just got mine to 🇬🇧 can’t wait to give it a go 👊👊👊

[@jeffb8437]

What’s the model number of that flow gauge?

[@accutools6288]

Dwyer HFA-2-100, calibrated for air at 4.0 specific gravity @100 psi, 70 degrees F. You have to put a valve in parallel with it to recalibrate it to your vacuum pump.

[@mikerefrigeration5736]

Question: When making repairs on a system (or replacing a compressor). If we are replacing the filter drier, is moisture really a cause for concern? I would assume at that point proper de-gassing is more a priority rather than trying to remove moisture with the pump. So a vacuum of 5000 microns or less should be OK. But a vacuum under 500 microns with a 10 minute decay test would be better.

[@markm0000]

The filter drier can only hold a few teaspoons of water until it fills up and stops absorbing. Then you have water circulating around with the compressor oil. That causes acid to buildup and damage the compressor.

[@yorkrojas1452]

Science!! Thanks!!

[@scottjones7279]

You need to stop making these videos they cost me too much money.😊

[@Mikecianfrocco]

1/4” hoses 1 cfm that’s garbage !

[@measureQuick]

Actually about .5 to .7. Maybe less.

[@DJV94022]

1/4 hoses makes more sense to do the job for 3/8 copper line..but yeah a bigger hose should def be connected to the bigger copper line whether it be 3/4,7/8 or 1 inch copper suction
