Connection Set Heatpex N 20-25 (nuts, seals, locking rings — 4 pcs each) HEATPEX 11002002500T

Heatpex Connection Set N 20-25 contains the fastening and sealing components required to assemble or repair pipe joints for 20–25 mm pipe systems. The kit includes four nuts, four sealing rings and four locking rings designed to match Heatpex fittings. It is intended as a direct replacement or installation set where original Heatpex connection parts are specified, supporting plumbing and heating applications that use 20–25 mm diameter pipes.

Advantages

The set groups compatible nuts, seals and locking rings in one package, reducing the need to source individual parts. Components are sized for 20–25 mm pipe connections, ensuring dimensional compatibility with Heatpex fittings and maintaining proper sealing and mechanical retention. Offering a matched set helps simplify installation and maintenance tasks by providing the standard consumables typically required for connection points.

Suitable for

• Installation of 20–25 mm plumbing and heating pipe connections using Heatpex fittings
• Maintenance or repair of existing Heatpex connection joints
• Professional installers and service technicians working on residential and light-commercial systems
• Stocking as spare parts for scheduled maintenance or emergency repairs

When it may not be suitable

This connection set is specifically sized for 20–25 mm pipe systems; it is not suitable for connections with substantially different pipe diameters. The kit contains only nuts, sealing rings and locking rings and does not include pipes, fittings, valves or tools, so additional components may be required for a complete installation.

Key specifications

• Compatible pipe diameter: 20–25 mm
• Contents: 4 nuts, 4 sealing rings, 4 locking rings
• Intended application: plumbing and heating connection joints
• Material types: metal nuts and elastomeric sealing rings (as used in Heatpex connection systems)

How to use

Select the appropriate position on the 20–25 mm pipe and corresponding Heatpex fitting. Slide a locking ring and sealing ring into place as required by the fitting design, then secure with the nut. Tighten to the manufacturer’s recommended torque or until the connection is secure and leak-free. Replace existing worn nuts and seals with the new components to restore sealing performance during maintenance or repair.

What to consider before purchase

• Confirm the pipe outer diameter and compatibility with Heatpex N 20–25 connections
• Verify that only nuts, sealing rings and locking rings are required; purchase additional fittings or tools if necessary
• Ensure material compatibility with the fluid, temperature and pressure conditions of the system

Usage recommendations

Store components in a dry place and inspect sealing rings for damage before installation. Follow Heatpex fitting assembly instructions and torque recommendations. Replace all sealing components on a joint during maintenance to ensure reliable sealing.
