Key Features of Boshart CE PEX x MPT 90° Elbow
This 304 stainless steel corrosion-resistant PEX elbow fitting resists dezincification in highly acidic water conditions.
The large internal diameter maximizes water flow through the connection compared to standard poly or metal insert fittings.
An integral stop tab ensures proper installation depth of the tubing over the cold expansion PEX fittings.
The cold expansion connection method provides a secure mechanical seal formed by the natural memory of PEX-A tubing.
These stainless steel PEX fittings operate safely in plumbing systems rated up to 100 PSI and 180°F.
The threaded end conforms precisely to ASME B1.20.1 standards to guarantee secure mechanical joints.

Installation Method
Slide the appropriate ASTM F1960 expansion collar onto the end of the PEX-A tubing.
Use an expansion tool to expand the pipe and collar simultaneously according to the tool manufacturer's instructions.
Insert the cold expansion fitting into the expanded tubing until the pipe reaches the integral stop tab.
Hold the fitting in place for a short duration while the PEX-A tubing shrinks back down to create a secure connection.
Connect the MPT end to the corresponding female threaded component using approved thread sealant.
Applications & System Integration
Residential potable cold and hot water distribution lines.
Corrosive and aggressive water environments require high chemical resistance.
Hydronic heating system network connections.
Commercial plumbing infrastructure and facility piping.
Areas prone to dezincification where traditional brass components fail.
Direct transitions between PEX-A networks and threaded valves or equipment.
Compliance & Certification
These ASTM F1960 certified PEX fittings for hot and cold water systems comply with NSF/ANSI 61 and NSF/ANSI 372 standards for lead-free potable water safety. They also meet cUPC and CSA B137.5 plumbing standards.

Frequently Asked Questions
What are the compatibility guidelines for PEX-A pipe with stainless steel expansion fittings?
ASTM F1960 cold expansion fittings require PEX-A tubing because this pipe type has the necessary thermal memory to expand and shrink tightly around the fitting. These fittings must not be used with PEX-B or PEX-C tubing.
What is the expected lifespan of stainless steel PEX fittings?
304 stainless steel PEX fittings offer long service life, especially in aggressive or acidic water conditions. Unlike brass, stainless steel is not subject to dezincification, helping maintain structural integrity over time.
Can a crimp tool be used to install this PEX x MPT elbow?
No. This fitting is designed strictly for the ASTM F1960 cold expansion method. Installation requires a compatible PEX expansion tool and expansion collar. It is not compatible with crimp rings or clamp systems.
Is this stainless steel PEX elbow safe for drinking water systems?
Yes. The fitting is manufactured from 304 stainless steel and is certified to NSF/ANSI 61 and NSF/ANSI 372 standards for potable drinking water applications.
Does this PEX elbow restrict water flow?
No. Cold expansion fittings maintain a larger internal diameter compared to insert-style crimp fittings, helping reduce flow restriction and minimize pressure drop within the system.
What are the pressure and temperature limits for this fitting?
This fitting is rated for a maximum working pressure of 100 PSI at 180°F (82°C). Final system limits depend on the specifications of the installed PEX-A tubing.
How can I ensure proper insertion depth during installation?
The fitting includes an integral stop tab. During installation, insert the fitting into the expanded PEX-A tubing until the edge of the pipe and collar sits firmly against this stop tab.
