The Complete Installation & Finishing Kit for Heated Towel Rails

Complete the installation of your heated towel rail, towel radiator or central heating radiator with this professional-grade 1/2" BSP chrome blanking plug, bleed valve and concealing cap kit. Manufactured from heavy-duty solid brass with a polished chrome finish, the components provide a durable, corrosion-resistant and watertight solution for modern central heating systems.

Engineered with universal threads, the heavy-duty solid brass core delivers a long-lasting, leak-proof seal. The high-shine chrome concealing caps push-fit smoothly over the exposed valve heads, hiding raw metal pins to perfectly complement your chrome heated towel rails and designer radiators. Suitable for both new radiator installations and replacement applications, this kit combines reliable sealing performance with a clean, finished appearance.

Key Product Features

• Universal Compatibility: Fits most modern UK central heating radiators, designer panels, and ladder towel rails with standard 1/2" connections.
• Leak-Free Protection: Functional plugs are equipped with premium rubber EPDM O-rings for secure, compression-sealed performance.
• High-Shine Chrome Finish: Includes matching push-fit decorative caps that snap directly onto the brass fittings to deliver a mirror-like look.
• All-In-One Solution: Eliminates the need to buy venting pins and blanking caps separately, packaging aesthetic upgrades with crucial plumbing utility.

What's Included in the Box?

• 1 x 1/2" BSP Manual Bleed Valve (Air Vent for releasing trapped air)
• 1 x 1/2" BSP Radiator Blanking Plug (To permanently seal the opposite top port)
• 2 x Chrome Push-Fit Concealing Cover Caps (For a mirror-polished finish)
• Pre-installed EPDM O-Rings (Premium rubber washers for water-tight compression)

Installation Guide & Fitting Instructions

Installing this kit requires no specialized plumbing expertise. Simply screw the manual bleed valve and blanking plug into the radiator's threaded top ports. Tighten securely using an appropriate spanner or Allen key, ensuring the pre-installed EPDM rubber O-rings are squarely seated against the radiator entry to create a compressed, watertight seal. Once tightened, line up the decorative chrome caps and press them directly onto the brass fittings until they sit flush against the top bars for a clean, tool-free finish.

This universal hardware kit is fully compatible with the vast majority of UK wet central heating systems. It is engineered specifically to match standard 1/2" BSP connections on modern chrome heated towel rails, ladder towel radiators, horizontal designer radiators, vertical designer panels, compact single/double panel radiators, and traditional steel column radiators.
