SeaTech PEX fittings

[Paul]

Has any one used plastic SeaTech Fittings?   www.seatechinc.com

These fittings work the same as Sharkbite fittings.

We will use all ½ ID 5/8 OD PEX tubing. The pump size is 1/2 " and I see no reason to use larger tubing.

Paul,
   This may be the brand I am using. I refer to all this type fittings as "SharkBite", kinda like refering to all refrigerators as "Frigidaires"  We purchased our at a local Lowe's.  When the water dries up from the rain, I will see if I have any still in the packaging.  Jack

I may be completely wrong here, but these are what I know as "Sharkbite" fittings:

These are the Seatech fittings sold at most major home centers:

They look a lot different to me. But maybe that's just me.

And Yes, I did drive by a Holiday Inn Express once and even thought about stopping there, but liked sleeping in my own bed in the bus a lot better!

I used these fittings for my misters and will use them for my next conversion.  Most all air fittings on trucks now use a similar fitting for brake lines.  It's nice since you can also take them apart quickly too.  Good Luck, TomC

We are useing the same type of fittings on our robot end effector. They have held up great, even with all of the quick movement, no leaks. The best part is you can change out a line pretty fast, sure beats the old way using ferrules and wrenches. 

Don't ya just love progress!

Hey Dallas, I do stay at a Holiday Inn when traveling, and I even get free cookies and milk!

I used some of these in a pinch when I didn't realize Home Depot carried the Sharkbite fittings.

They don't seem to bite as tight as the Sharkbite fittings.  I was also concerned that vibration might cause them to come loose.  Sharkbite fittings aren't that much more expensive than the Seatech fittings.

I am reactivating this thread to explore this one question.  Are sharkbite type PEX fitting suitable for a vibration environment, such as a bus. 

Or should I go the route of buying the crimper tool and such?

Even in a residential setting I was warned to never use Sharkbite fittings anywhere they cannot be accessed since they can spontaneously develop leaks.

The crimp-on connectors are great, but if installing in close quarters it can be difficult to get the tool on the fitting to crimp. This year I replumbedb most of my house when we removed the galvanized piping, and I decided to splurge and buy the Milwaukee tool for using the expansion fittings.

Doing the retrofit involved putting fittings in some really difficult to reach places, and the expansion piping is handy for this as you can expand it and it stays that way for long enough to push the pipe over the fitting. All you have to do is hold it in place till it tightens up and you're done.

I can see how there will be many places in a bus conversion where you'll be working in close quarters and where the expansion fittings will make the work easier. You also get better water flow in the same size fittings using the expansion ones vs. the crimp-on fittings.

I used these, as long as you don't bend the pex wrong when turning a corner on the line. Every bend is 2 less chances of a leak. If it gets bent to hard when installing the corner, it will restrict flow, lvmci.

I am familiar with the crimp on rings, but I'm going to have the explore the expansion method.  Thanks

I use the Zurn expansion fitting,doing a conversion from the start there should be no close quarter's ,LVMCI method works good too I used those in some areas.Richards crimping machine is nice but costs it does take a lot of room for the Milwaukee or Dewalt .The Zurn pinch rings are easier to use than the squeeze type and can be removed with the Zurn tool,the preset Zurn pinch rings are about all I use.Buy the PEX pipe in straight lengths it is a lot easier to do a bus with than fighting the rolls BTDT

Have you priced copper lately,Pex is cheaper and better, in freezing weather it wont bulge and break like copper it is really good for RV use not like the old gray poly pipe that was used for years in RV's
