A real question

[BamaCracker]

I am getting ready to break out a new line of 410A equipment, (against my wishes) and there is major discussion about whether we need to keep standard sized schrader fittings or use the larger ones.

What would you like to see?

And more importantly, what does Carrier, Trane and Lennox do?

I know Amana uses a special fitting and adapter, but other than that, I know nothing. Enlightne me.

[JAMES 3528-old]

are 410 gauges a different size?

[workinlate]

Keep the same fitting. The jug of 4-10 has the fitting and most of the manifold's have the same fittings....
Look at 134-a auto manifold special fitting's....a few prep table condensers factory 134-a = standard fitting......134-a jug stanard..
This is just my retarded opinion besides when they made r-22 they didn't have special fittings (I think people were alot better trained and more concerned then and I think that is your point....)

Well that was alot of nothing from me:D

I'd rather the standard fittings. I might have to buy a new gage set for 410A but I'd like to use the same sized hoses.

[jmac00]

and PLEASE, keep the pressures down, I never did volunteer for the BOMB SQUAD,

It makes me a little nervous working on equipment with a 400psi working pressures:(

Amana's new line of R410a systems will have the standard 1/4" fittings, against my rants to the marketing department.

[diceman]

and while you're at it, keep it 22 as well. Some of these bright ideas these guys come up with, I need to retire soon. I about had it.

Ya r-22 will be around for another 15-20 years, I hope, they should stop using it 24 hours AFTER I retire :rolleyes: :confused:

I want to keep standard fittings, but my team leader seems to think it is a safety hazard or something.

Most of you know my thoughts on 410A. It sucks! If we have to change (and manufacturers have to change in 2010 by federal law) I'd much rather see us go to 407C, which is the "Green" refrigerant of choice in Europe.

So, on to my second question, which none of you addressed (except Robo):
What are the other guys doing? Especially Carrier.

[RoBoTeq]

Everybody uses standard, except the current Amana line which requires adaptors.

All Amana R410a will be using Copeland scroll compressors. Is Purina going to use a Bristol?

stanard fitting's on puron units..........

[Ranger]

Lennox uses standard as well.

[Pegleg Smith]

From a safety stand point it would make better sense to use a different sized fitting. That way the techs would be forced to use the proper gage sets. The hoses all have their burst ratings printed on them. Older, deteriorated hoses lose their rating and therefore could be considered dangerous if used with 410A. If safety was the primary factor in using larger fittings then I think that it would be justified. You could boast how protecting the tech is important to you guys.
If safety is a primary concern you could provide entire gage sets, equipped for the different port sizes, with each unit sold and included in the cost of the unit at a nominal cost. That would outshine any of the competition and provide techs with a needed tool.

[RoBoTeq]

That's what Amana engineering felt also Peg. Unfortunately marketing wins in these cases.

You know what happens when you see a marketing guy walking down the street with a used car salesman?

You lose any respect you might have had for that car salesman.

By the way.........The king valves are the best..Carrier used them on the tech 2000 box only. The cube uses standard and the package unit are standard but without a liquid line fitting hot gas only....kinda cheap if you ask me.....

[RoBoTeq]

The Amana units are using back seating valves also.

[BamaCracker]

I'll tell you why I never cared for King valves:

The guy there before me always managed to bugger up the valve handle so my reefer wrench no longer fit, using his ViseGrip pliers I guess.

They ALWAYS leak eventually, and no one ever seems to replace them. You find them piped around and sometimes not even a saddle valve installed.

How many times you ever seen a new guy front seat a valve and leave it, not realizing what he did?

Besides all that, I now have a new reason for not liking them. . . . . . . my 2003 objective at work calls for me to locate and remove $250,000 worth of manufacturing cost. At an average of $15 each, I can realize my entire objective by doing away with them! :D

The battle over schraders is won though. Based on the fact that Carrier and Trane use stanard valves, and Amana is changing over due to customer complaints, I was able to convince BigBoy and his buddies that standard size is best.
