Internal External

Flanged Valve & Fitting Jacket Options

Cast Iron Strainer

For flanged strainer valves and larger strainer bodies on commercial or industrial pipework.

Internal External

Flange

For standard flange fittings requiring removable thermal insulation and access.

Internal External

Iron Globe Valve

For globe-style flanged valves. Send measurements if the valve body is unusual or oversized.

Internal External

Iron Gate Valve

For larger flanged gate valves commonly found on commercial and industrial systems.

Internal External

Flanged 3-Way Valve

For 3-way valve bodies used across heating, mixing and control applications.

Internal External

Blanked Flange

For blank end flanges and capped flange arrangements needing insulated coverage.

Internal External

For flanged non-return and check valves on commercial and industrial pipework.

Internal External

Bespoke Valve Jacket

For non-standard flanges, strainers, globe valves, check valves or unusual fittings, send photos and dimensions for a made-to-spec jacket check.

Steam Jacket Option

Steam services can need a more specialist jacket route. Use this page when the valve or fitting is part of a steam installation.

Trade SupportSend photos and dimensions if you need help selecting the closest jacket type.

Not sure which valve you have?

Send us a clear photo of the valve, the pipe outside diameter, overall valve length, overall valve height and whether it is for internal or external use. We can help point you toward the closest standard jacket or a bespoke made-to-spec option.

How to Choose the Correct Valve Jacket

For the best match, confirm the valve type, pipe outside diameter, overall valve length, overall valve height and whether the jacket is for internal or external use.

Choose internal jackets for plant rooms, boiler rooms, risers and indoor services.
Choose WeatherPro jackets for external or exposed pipework.
Choose insulated steam jackets for steam services and higher-temperature applications.
For unusual fittings, send us photos and dimensions for a bespoke check.

Internal, WeatherPro External & Insulated Steam Jackets

Internal Valve Jackets

Internal jackets are designed for indoor plant rooms, boiler rooms, risers and service areas where the valve needs thermal coverage while remaining accessible for inspection and maintenance.

Ideal for indoor mechanical services
Removable for maintenance access
Useful around valves, unions, flanges and fittings

View Internal Jackets

WeatherPro external thermal valve jacket

WeatherPro External Jackets

WeatherPro jackets are designed for external or exposed areas where the jacket also needs a tougher outer finish suitable for weather-facing conditions.

For external and exposed services
Helps protect valves from weather exposure
Useful for plant areas and outdoor pipework

View WeatherPro Jackets

Insulated Steam Jackets

Steam jackets are for steam pipework, steam valves and higher-temperature service conditions where a standard valve jacket may not be the correct route.

For steam service applications
Project-specific checking recommended
Suitable jacket selection depends on temperature and fitting type

Thermal Jackets Compared with Pipe Insulation & Protection Products

Thermal valve jackets are one part of the full pipe insulation system. They are especially useful where standard pipe sections or rolls cannot neatly cover a valve, flange or fitting while still allowing access.

Thermal Valve Jackets

Best for valves, flanges, strainers and fittings where removable insulation is needed for maintenance access.

Pipe Insulation

Best for straight pipe runs, heating pipework, chilled-water services, HVAC, risers and mechanical pipework.

Insulation Cladding

Best for protecting insulation from weather, impact or damage on external and exposed pipework.

Trace Heating

Best for frost protection where insulation alone is not enough to protect pipework in low-temperature conditions.

Accessories

Includes tapes, labels, fixings, adhesives and finishing products needed to complete the insulation system.

Sprinkler Systems

Useful for fire sprinkler pipework where trace heating, insulation and suitable control products are required.
