AHEAD OF THE FLOW
®
Look to NIBCO for Leadership on PEX Piping Systems
NIBCO
®
is proud to offer NIBCO
®
PEX, our potable water piping system. With over 100 years of experience you can trust NIBCO to
provide the highest quality PEX product.
NIBCO
®
PEX Pipe is produced through the PEX-c method that uses an electron beam to change the molecular structure of polyethylene,
giving it enhanced physical properties over conventional polyethylene. Available in 3/8” to 1-1/4” copper tube size, NIBCO sets a new
standard in PEX plumbing products.
NIBCO
®
PEX Pipe Offers Significant Advantages:
• NIBCO
®
PEX contains UV stabilizers that protect it against damage from short-term
exposure to sunlight.
NIBCO
®
PEX is pliable – it can be easily straightened after removal from the coil.
• NIBCO
®
PEX has greater dimensional stability. We hold the outside pipe diameter dimensions of
our pipe to strict tolerances. This means a better fit for you with no sliding of copper crimp rings
on the pipe.
• NIBCO
®
PEX is chlorine-resistant. It is a viable solution for aggressive water conditions.
NIBCO
®
PEX is non-toxic. It employs no toxic chemicals in its manufacture, unlike other PEX
manufacturing methods.
• NIBCO
®
PEX will not leach taste or odor. It keeps water clear and clean with no odor due to
leaching from the pipe.
• NIBCO
®
PEX’s opaque color limits light from supporting bacteria and algae growth.
• NIBCO
®
PEX pipe is quiet. It insulates against water hammer and noise in the pipe.
• NIBCO
®
PEX’s natural insulation properties keep hot-water hot and cold-water cold.
• NIBCO
®
PEX requires fewer fittings in a typical installation and is easier to install.
• NIBCO
®
PEX expands if water freezes in the pipe.
• NIBCO
®
PEX is more resistant to abrasion than steel or copper.
• NIBCO
®
PEX offers you three different connection methods - copper crimp ring, copper crimp sleeve,
and stainless steel sleeve.

NIBCO PEX Tube Markings Explained

Crimp Tool Usage and Adjustment

5-Step Method for Crimp Connection

Step 1: Squarely Cut Pipe

Ensures a proper connection by cutting the pipe squarely; jagged cuts can lead to failure.

Step 2: Position Crimp Ring

Step 3: Insert Fitting and Position Ring

Step 4: Crimp Connection

Step 5: Inspect Crimp Connection

5-Step Method for Stainless Steel Sleeve Connection

Step 1: Cut Pipe for Sleeve Connection

Ensures a proper connection by cutting the pipe squarely; jagged cuts can lead to failure.

Step 2: Position Stainless Steel Sleeve

Slide the correct size stainless steel sleeve over the PEX pipe until it bottoms out, checking the view hole.

Step 3: Insert Fitting for Sleeve Connection

Step 4: Crimp Stainless Steel Sleeve

Step 5: Inspect Sleeve Connection

Push 'N Go Installation Instructions

Step 1: Prepare for Push 'N Go

Prepare your pipe and fitting, ensuring they are ready for connection.

Step 2: Connect Push 'N Go Fitting

Simply push the PEX pipe into the fitting until it stops for a secure connection.

Push 'N Go Features and Benefits

Highlights quick-connect, tool-free installation, disassembly, and material benefits of Push 'N Go fittings.

Push 'N Go Performance Standards

Lists performance standards like ASTM F877 and NSF-PW for PEX hot and cold-water distribution systems.

NIBCO PEX Pipe Basics

Minimum Bending Radius Guidelines

Provides minimum bend radius specifications for NIBCO PEX tubing sizes to prevent damage.

Proper Support of NIBCO PEX Pipe

Details guidelines for supporting PEX pipe to prevent strain, including spacing and support types.

Allowing for Expansion and Contraction

Leave Extra Tubing at Ends

Leave extra tubing at both ends of the run for easier connections to fittings, fixtures, and manifolds.

Keep Hot and Cold Lines Separate

Bundle hot and cold lines separately to avoid heat transfer issues and maintain insulation properties.

Caution When Soldering Near PEX

Solder adapter fittings first, and always keep soldering tools and open flames away from PEX pipe.
