## Summary description

SOL-ARM KOREK PE 40 is a SOL-ARM check/drain-back valve, model PE-67-040. Designed for solar thermal systems, the valve enables controlled drainage and prevents backflow. It is used to protect collectors and piping from stagnation and freeze damage, and to ensure proper circulation and system shut-off during non-operation or maintenance.

## Long description

SOL-ARM KOREK PE 40 is a polyethylene drain plug designed for plumbing systems where a robust, corrosion-resistant closure is required. Manufactured for compatibility with SOL-ARM fittings, this PE 40 plug provides a tight seal and long service life in applications involving non-aggressive water and wastewater. The simple geometry and durable polyethylene construction make it suitable for both installation and occasional removal during maintenance.
Advantages
The polyethylene material offers chemical resistance to many common substances encountered in residential and light-commercial drainage systems while remaining lightweight and easy to handle. The design ensures a reliable seal under standard operating conditions and reduces the need for additional sealing materials. Its compatibility with SOL-ARM components simplifies parts selection and replacement, and the smooth surface supports easy cleaning and inspection.
Suitable for
 Sealing open ends of PE piping and fittings in plumbing and drainage systems
 Temporary or permanent closure of service lines during maintenance
 Use in residential, commercial, and light industrial wastewater applications
Key specifications
 Material: polyethylene (PE)
 Nominal size: 40 (suitable for PE 40 fittings and pipes)
 Construction: one-piece molded plug
 Surface: smooth, non-corroding
 Suitable medium: water and wastewater (non-aggressive)
How to use
Before installation, ensure mating pipe or fitting faces are clean and free of debris. Insert the SOL-ARM KOREK PE 40 into the pipe end or fitting until fully seated, applying steady pressure to obtain a firm fit. For permanent installations, verify alignment and seating; for temporary closures, confirm the plug can be removed without excessive force. Inspect the seal after filling the system to detect any leaks and re-seat if necessary.
Usage recommendations
Do not use this polyethylene plug with aggressive chemicals, petroleum-based solvents, or in high-temperature applications that exceed the material's recommended limits. Store the plug away from direct sunlight and prolonged UV exposure to maintain material properties. When used in buried installations, follow local codes for bedding and protection to prevent mechanical damage.
