Couplings

  • Split Couplers
  • Water Tight Gasket
  • Reducers
<

Picture
A split coupling will wrap around the corrugations or "ribs" of the pipe. With smaller diameters like 4" - 6" you can seal and secure these connections with our tile tape. In larger diameters, we provide zip ties that will secure the coupling to the ribs of the pipe. 
​
Available in: 2", 3", 4", 5", 6", 8", 10", 12", 15", 18", 24", 30", 36" & 48"

This connection will provide a great water-tight seal at the seems of pipe. This gasket is designed to work between pipes of the same inside diameter. 
Picture
This connection is great when you need to tie in a smaller line to a main line. Be careful not to have the water flowing from the lager to the smaller size, this will almost always create a back up of water flow. 
We offer reducers in a variety of sizes and steps from 4" to 60" diameters.

Tees 

  • Straight Tee
  • Reducing Tee
  • Cross Tee
  • Saddle Tee
<

Picture
Straight tees are used when you need to join pipe of the same size from 3 directions. These work great when creating a grid system in an agricultural field or in your yard to move water away from your house. 

Available in: 4", 6", 8", 10", 12", 15", 18", 24", 30" and 36"
**Larger diameters are special order upon request

Picture
Reducing tees are commonly used to connect smaller perpendicular grid lines to a large main drainage line. These are an efficient way to keep water flowing. 

Available in a variety of reductions from 60" to 4"
*Larger diameters may require more lead time. 

Picture
This cross tee will be a useful intersection, and split couplers will provide a soil-tight seal on all 4 unions. 
Available in: 4", 6", 8", 10", 12", 15", 18" & 24"
Picture
Saddle tees make for great adaptions from larger pipe to smaller, without having to incorporate an actual tee. The "saddle" will wrap around your larger main line and you just have to core a hole for smaller line you want to incorporate. 
Available saddle sizes are: 10", 12", 15", 18", 24" & 30"
       with reducing lines from: 4" to 15"

Elbows

  • 22 1/2 Degree
  • 45 Degree
  • 90 Degree
<
>
Picture
Our smallest available angle is 22-1/2 degrees. These elbows are plain ended and require split couplers to continue your drain line. 
Available in: 4", 6", 8", 10", 12", 15", 18", 24", 30", 36", 42", 48" & 60"
Picture
The next step in our elbow systems is 45-degrees. Also a plain ended fitting that requires split couplers to join drain lines. 
​Available in: 4", 6", 8", 10", 12", 15", 18", 24", 30", 36", 42", 48" & 60"
Picture
Our 90-degree elbows come as a 2-part elbow creating a sharp 90-degree turn. Split couplers are also required to join drain lines together. 
Available in: 4", 6", 8", 10", 12", 15", 18", 24", 30", 36", 42", 48" & 60"

End Cap

Picture
Our external end caps come gasketed to fit into the bell end of our dual wall pipe. If you are working with a cut-off piece of pipe, a split coupler will also help cap of your drain line. 
​Available in: 4", 6", 8", 10", 12", 15", 18", 24", 30", 36", 42", 48" & 60"
