Primary Pro Rubberlined Pipe Clip | 22mm/28mm Insulation | AS008

Description

The Primary Pro Rubberlined Clip is designed to fix and support 22mm and 28mm Primary Pro insulated pipework along external heat pump flow and return runs. Once insulation and protective coating are fitted around a primary pipe, the overall assembly is considerably larger in diameter than the bare pipe underneath — a standard pipe clip is therefore unsuitable, as it will compress or distort the insulation rather than support it correctly.

Sized specifically for the completed insulated pipe assembly, this clip holds the run securely to a wall or other mounting surface while its rubber lining protects the external finish from direct metal contact. This is a particularly important detail in warm climates, where an unlined metal clip can become hot enough to bond to the insulation surface — the rubber lining prevents this while also cushioning the pipe against vibration.

Please Note

This clip is sized for the complete insulated pipe assembly, not the bare pipe. Do not substitute a standard pipe clip sized to the pipe diameter alone, as this will compress and damage the insulation.

Key Features

Sized for Insulated Pipework

Fits over the complete insulated assembly for both 22mm and 28mm Primary Pro Insulation, rather than the bare pipe diameter.

Rubber-Lined Construction

The rubber lining protects the insulation's outer finish from direct contact with the metal clip body, reducing wear at fixing points.

Prevents Heat Transfer to Insulation

In warm climates, an unlined metal clip can become hot and adhere to or damage the insulation — the rubber lining avoids this.

Maintains Insulation Efficiency

Correctly fitted clips help protect against water ingress at fixing points, preserving the insulation's thermal performance over time.

Suitable for New Builds and Retrofits

Works equally well on new heat pump installations and remedial upgrades to existing external pipe runs.

Simple External Fixing

Fits to masonry, render or other suitable mounting surfaces using standard threaded fixings.

Frequently Asked Questions

What sizes of insulation does this clip fit?▼

This clip is designed for Primary Pro 22mm and 28mm insulation, sized to the completed insulated pipe assembly rather than the bare pipe diameter.

How far apart should the clips be spaced?▼

Midsummer recommends fitting one clip every 2 metres of insulated pipe run, with additional support at bends and connection points.

Why use a rubber-lined clip instead of a standard pipe clip?▼

A standard clip sized to the bare pipe will compress and damage the insulation. The rubber lining also prevents the clip from becoming hot enough to bond to the insulation in warm conditions, unlike an unlined metal clip.

Can this clip be used on existing installations?▼

Yes, it is suitable for both new heat pump installations and remedial upgrades to existing external insulated pipe runs.
