Pre-Made Insulation Jackets — Box of 100

The PrimaryPro 100x Pre-Made Insulation Jacket is a trade bulk pack of 100 Primary Pro factory-made insulation jackets, designed for professional ASHP installers and merchants handling high volumes of heat pump installations. Buying in a bulk box reduces cost per unit, eliminates repeated small orders, and keeps a full stock of valve jackets on the van or in the branch for every job.

Primary Pro insulation jackets are manufactured from the same UV-resistant, waterproof, weather-proof material used across the Primary Pro pipe insulation range. They provide a purpose-made, close-fitting insulation shell for Intatec external heat pump valves — protecting both the valve body and the pipe connection from the elements, preventing heat loss, and maintaining system efficiency. Each jacket is ready to use straight from the box — no on-site cutting or shaping required for a standard Intatec valve installation.

What Are Primary Pro Pre-Made Insulation Jackets?

When insulating external ASHP pipework, it is not enough to insulate only the pipe runs — every external fitting, including antifreeze valves and isolation valves, must also be fully insulated and sealed to protect system efficiency and prevent component damage.

Cutting and wrapping individual lengths of Primary Pro insulation around valve bodies on site is time-consuming and difficult to achieve neatly. Primary Pro developed pre-made insulation jackets in collaboration with Intatec specifically to solve this problem. Each jacket is factory-manufactured from Primary Pro insulation material, pre-shaped to fit a specific Intatec valve exactly — the installer simply slides the jacket over the valve, seals with Primary Pro Bond and Seal (AS001), and the fitting is fully insulated, weatherproof, and professionally finished.

This approach is particularly valuable when working against the weather or on a time-pressured installation — the pre-made jacket removes the need for any on-site shaping or fitting of raw insulation around irregular valve bodies.

Jacket Variants in This Range

Item Code	Jacket Type	Fits	Connection Size
AS32	Antifreeze Valve Jacket	Intatec 28mm (1") Antifreeze Valve	1" / 28mm compression
AS52	Antifreeze Valve Jacket	Intatec 35mm (1-1/4") Antifreeze Valve	1-1/4" / 35mm compression
AS33	Flat Face Lever Valve Jacket	Intatec 28mm (1") Flat Face Lever Ball Valve	1" / 28mm
AS53	Flat Face Lever Valve Jacket	Intatec 35mm (1-1/4") Flat Face Lever Ball Valve	1-1/4" / 35mm

Please confirm variant when ordering. The 100-unit bulk pack is available for each individual jacket code (AS32, AS52, AS33, AS53). Please specify which jacket type is required when placing your order. If your installations use a mix of valve sizes, the 50-unit pack is also available for more flexible stocking.

Why Buy in Bulk?

For ASHP installers and merchants, keeping valve jackets on hand as a standard stock item makes practical sense. Every external ASHP installation using Intatec antifreeze or isolation valves requires at least one jacket per valve — and many installations use multiple valves. Running out of jackets on site means either returning to collect stock or leaving a fitting uninsulated, neither of which is acceptable on a professional installation.

The 100-unit bulk pack reduces cost per jacket compared to smaller pack sizes, minimises ordering frequency, and ensures enough stock to cover multiple jobs without repeated reordering. For branch stock, the 100-unit pack is the efficient choice for steady-volume Primary Pro merchants. For installers who carry mixed jacket sizes, the 50-unit pack is also available.

Frequently Asked Questions

Do I need to use Bond and Seal with the pre-made jackets?

Yes. The jacket itself provides the insulation and physical protection, but Bond and Seal AS001 is required to seal all joints and edges — particularly where the jacket meets the pipe insulation and at any open edges. Without sealing, moisture can enter at the joints and reduce the insulation's effectiveness over time. Apply Bond and Seal generously around all contact edges and allow to cure fully before exposing to rain.

Which jacket fits which Intatec valve?

AS32 fits the Intatec 28mm (1") antifreeze valve. AS52 fits the Intatec 35mm (1-1/4") antifreeze valve. AS33 fits the Intatec 28mm (1") flat face lever ball valve. AS53 fits the Intatec 35mm (1-1/4") flat face lever ball valve. Please check the valve model and connection size on site before ordering to confirm the correct jacket variant. The 28mm and 35mm connection sizes refer to the compression fitting dimension, not the nominal bore of the pipe.

Are these jackets only for Intatec valves?

The pre-made jackets are designed and manufactured to fit specific Intatec valve profiles. They will not provide a correct fit on valves from other manufacturers, as the external valve body geometry will differ. For non-Intatec valves, Primary Pro pipe insulation can be cut and mitred to shape around the valve body on site, using Bond and Seal to seal all joints and edges.

Can the jackets be used in all weather conditions?

Yes — Primary Pro insulation jackets are manufactured with a UV-stable, weatherproof outer coating that is active from the moment the jacket comes out of the box. Unlike standard foam lagging, they do not need to be painted or treated before outdoor use and will not degrade under direct UV exposure. Bond and Seal should be applied in dry conditions where possible and allowed to achieve a surface cure before exposure to rain, though it is suitable for use in damp conditions when necessary.

How do I maintain the jackets after installation?

Inspect during the annual heat pump service. Check that the outer surface remains intact and that Bond and Seal joints show no cracking or gaps. If the outer coating shows discolouration or surface wear, apply Primary Pro Maintenance Coat IG005 to restore the protective finish. Installations not exposed to direct south-facing sunlight may not require recoating within the first five years. Any Bond and Seal joints that show shrinkage should be topped up to maintain the weatherproof seal.
