Blue British Hose Clamps

The Blue Housing British hose clamp is a specific variant of the classic worm drive clamp, distinguished by its distinctive blue-colored housing (saddle). This color is not merely decorative; it is a visual identifier, typically signifying that the clamp is manufactured from high-quality, corrosion-resistant materials, making it suitable for specialized environments, particularly in the marine and automotive industries.

Key Features of British hose clamp

Blue Housing (Saddle):

The most recognizable feature is the bright blue saddle. This is usually achieved through a robust coating or, more commonly, by being made from Nylon or another engineering polymer.

The primary purpose of this polymer housing is to provide superior corrosion resistance and electrical insulation.

Stainless Steel Band and Screw:

The band and the worm screw are almost universally made from AISI 304 or 316 stainless steel.

This combination creates a clamp that is highly resistant to rust and degradation from saltwater, chemicals, and weather.

Classic British Worm Drive Mechanism:

It retains the efficient and reliable design of the traditional British worm drive clamp: a rolled, perforated stainless steel band that is drawn through the housing by turning the screw.

Advantages of British hose clamp

Elimination of Galvanic Corrosion: This is the most significant advantage, especially in marine applications.

On boats, when a standard stainless steel clamp with a metal housing is attached to a stainless steel fitting, it can create a bimetallic couple in the presence of seawater (an electrolyte), leading to intense localized corrosion known as galvanic corrosion.

The non-conductive, inert polymer housing electrically isolates the stainless steel band from the fitting, breaking this circuit and preventing this type of corrosive attack.

Excellent Overall Corrosion Resistance: The combination of a stainless steel band and a polymer housing immune to rust makes this clamp exceptionally durable in the harshest environments, including:

Saltwater (marine engines, bilge pumps, deck wash systems)

Chemicals (coolants, mild acids, fertilizers)

High humidity and constant moisture

Non-Marring and Safe:

The polymer housing is softer than metal and will not scratch or damage sensitive surfaces like polished brass fittings or painted surfaces.

It is safe to use on electrical grounding points as it will not conduct electricity.

UV Resistance: The blue polymer used is typically formulated to be resistant to degradation from sunlight, which is crucial for outdoor and marine use.

Easy Visual Identification: The bright blue color allows for quick inspection in crowded engine bays or on complex plumbing systems, making it easy to verify that the correct, marine-grade clamp has been used.
