PERLA Female Elbow 20mm x 3/4 inch Blue

The PERLA female elbow is a professional-grade plumbing fitting designed to facilitate a secure 90-degree transition in water distribution systems. Engineered with a 20mm pipe connection on one side and a 3/4 inch internal threaded connection on the other, this component provides a reliable solution for connecting polyethylene pipes to threaded valves, taps, or other system components. Its robust construction ensures long-term stability and leak-proof performance in various piping configurations.

Advantages

This fitting is manufactured from high-quality polypropylene, offering excellent resistance to chemical corrosion and environmental stress. The design ensures a smooth internal flow, minimizing pressure loss within the system. Its lightweight yet durable build simplifies handling during installation, while the precision-engineered threads provide a tight seal that withstands high-pressure environments. The blue and black color scheme allows for easy identification in complex plumbing layouts.

Suitable for

• Connecting polyethylene pipes to threaded metal or plastic components
• Residential water supply systems
• Irrigation and agricultural water networks
• Industrial fluid distribution lines

This fitting may not be suitable for high-temperature applications exceeding the thermal limits of polypropylene. It is also not intended for use with steam or aggressive chemical substances that are incompatible with the material properties of the fitting.

Key specifications

• Diameter: 20 mm
• Connection type: 3/4 inch internal thread
• Material: Polypropylene
• Angle: 90 degrees
• Maximum pressure: 16 Bar
• Color: Blue and black

How to use

To install the PERLA female elbow, ensure the pipe end is cut cleanly and deburred. Insert the pipe into the compression side of the fitting until it reaches the internal stop. Tighten the nut securely to create a watertight seal. For the threaded side, apply appropriate thread sealant, such as PTFE tape, to the male component before screwing it into the 3/4 inch internal thread of the elbow. Hand-tighten the connection and apply an additional quarter-turn with a wrench if necessary to ensure a firm fit without over-tightening.

What to consider before purchase

• Verify the outer diameter of your existing piping matches the 20mm specification
• Ensure the threaded component you are connecting to is a standard 3/4 inch male thread
• Check that the system pressure does not exceed the 16 Bar limit
• Confirm compatibility of polypropylene with the intended fluid type

Usage recommendations: Always inspect the O-ring and internal components for debris before assembly to ensure a perfect seal. Avoid using excessive force with metal tools on the plastic threads to prevent stripping or cracking.
