Checking the available jackets…
How do I check the correct jacket size?

First identify the valve connection and body type. Select a listed Bore Size (Pipe OD) and finish, then compare the actual valve body dimensions against the jacket specification. Pipe diameter alone does not guarantee fit. For actuators, unusual bonnets, special temperatures or non-standard dimensions, send a photo and measurements for a bespoke quotation.

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 thermal valve jacket

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 jacket

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.
