Waterway® Brand Poly Jets Home
All of the Waterway* Poly-Jet internals to the left will fit in the same jet body.

So, if you are looking to replace a certain jet, and you can't find it, or nobody has it in stock, you can substitute almost any one of those on the left. 

For this series of jets, Waterway produced 17 different versions that will accomodate this particular jet body. 

Note that all Poly Jets have a 5/16" orifices, unless yours is a Monster or Whirlpool Caged Style Jet. 

The Monster Caged Style jet (not pictured), was produced with 5/16", 3/8", 7/16", and 1/2" orifices.  The Whirlpool version has a 3/4" orifice.
 


In this image, a 210-7750 Pulsator is installed in the jet body.  If your particular jet has only one hole, then it's a 210-6750 'Whirly'.

For your own reference, the screw in threads on all of these jets will be 2.0 inches in diameter.
 



Now, you can see how all the other jets will fit into the Poly jet body...

What is shown here is the same jet with the adjustable collar removed, and then with it installed.  The image at the top right, shows a collar-less "Roto" jet, installed into a standard poly jet body.  The only real draw back to installing one of these in this fashion is that it is difficult to adjust the flow rate once the jet is screwed in.  But... it does work!
The Deluxe Series, is comprised of Standard face jets have a 3 1/2" diameter across the face.  The large face versions, are 4 1/4" diameter.  Reliable substition calls for being able to account for the entire jet facial diameter.. that is, if you've got standard jets with no face on them, (those that call for no outside ring to turn the jet on or off, and are simply -inserts-), and have at least 3 1/2" flat surface from the surface of the jet available, then you can be reasonably sure that a standard face jet will work in place of it.

Now, if you have whirly or pulsator jets installed in a particular jet bodies, and want to substitute jets with flanges such as the middle three jets in the picture at the top of the page, then you have two options. 

1.  If you have enough 'flat space', around the outside of the jet assembly, simply install one of these in it. 

2.  If you don't have any flat space, simply pry off the outside flange collar with a screwdriver, and install it in the jet body as shown here.
