What are the differences in the Red, White, and Blue PEX Pipe?
Other than the color, there is no difference. All three colors can be used for Hot or Cold water applications.
Can PEX Pipe be buried?
Yes. So long as you have good soil conditions: Flat with no hollows, no lumps, no rocks, and no other sharp objects.
Can PEX Pipe be buried under Concrete?
Yes. However, all fittings MUST be outside the concrete.
How do I calibrate my tool?
All tools are calibrated from the factory for the first 50,000 crimps. If your tool does need calibration please see our video about Plumbing Tools or download our tool instruction sheet to learn how to calibrate the tool.
Can I use PEX Pipe for Compressed Air Applications?
Can I use PEX Pipe for Hydronic Heat Applications?
Yes. However, you must use an Oxygen Barrier PEX Pipe. Most hydronic heating systems include some ferrous (iron-containing) components which will corrode over time if exposed to oxygen. Oxygen Barrier PEX tubing will prevent these components from rusting and keep them running smoothly.
What is the difference between a Copper Crimp Ring Connection and a Stainless Steel Cinch Clamp Connection?
Performance wise there is no difference between these two types of connections. The difference between them is the costs involved with their respective tools and the rings/clamps themselves.
Is PEX Pipe Freeze Proof?
Nothing is Freeze Proof. However, PEX Pipe is Freeze resistant. PEX Pipe will actually expand with the ice and retract upon thawing. In situations where copper or CPVC would burst the PEX will not. You should use the same insulation precautions with PEX Pipe as you would any other pipe.
I heard there were numerous lawsuits due to PEX Pipe flooding people’s homes, is this true?
No. Those lawsuits were in regards to Polybutylene (PB) Pipe. PB Pipe is gray in color and was used in the early 90s. PEX Pipe is a completely different technology and has been safely used for over 40 years.
Can I use PEX Pipe outside?
Yes. However, it MUST be protected from direct and indirect sunlight. PEX Pipe will start to become brittle and crack with continued exposure to sunlight.
Can I use PEX Pipe fittings on Polybutylene (PB) Pipe?
No. The inside diameter of PB is different than PEX. There is a ½" and ¾" coupling that you can use to transition PB to PEX. One side of the fitting is designed for the PB and the other for PEX.
Can the Push Fittings be buried?
Yes. However, you should wrap them with a plastic barrier prior to burying them.
Can the Push Fittings be used inside a wall?
Yes. Push Fittings are certified for in wall use.
What type of PEX is Apollo PEX tubing?
Apollo offers PEX-A (Expansion PEX) and PEX-B tubing. PEX-A tubing (Expansion PEX) is produced using the Peroxide or Engel method. Molecules of HDPE polymer are cross-linked during the extrusion process. PEX-B tubing is produced using the Silane or moisture-cured method. The molecules of HDPE polymer cross-linked after the extrusion process by exposing the tubing to water by a steam bath.
