How To Connect And Install Galvanised Pipe Clamp Fittings

Galvanised pipe fittings are a series of internal and external modular fittings that are designed for galvanized pipes of various sizes. They are designed specifically for the do-it-yourself (DIY) market, with ease of installation being a top priority in their design.

These fittings are made of galvanised steel, which makes them rust-resistant and durable. They are also easy to clean and maintain, and can be assembled/disassembled with ease. This easy assembly/disassembly also makes them extremely popular for customers erecting temporary structures.

Galvanised pipe fittings are available in a variety of shapes and sizes, so they can be used for a variety of applications. They are commonly used in the construction of outdoor structures such as handrails, balustrades, trolley bays, outdoor furniture & more!

What size pipe do galvanised pipe clamp fittings suit?

At Hammersmith we stock a range of different pipe fittings to suit the most common galvanised steel pipe sizes: 27mm, 34mm, 42mm, 48mm and 60mm in outside diameter. The nominal bore conversion for these pipe sizes are as follows: 20nb, 25nb, 32nb, 40nb and 50nb. See the conversion chart below for more information.

Types of galvanised pipe clamp fittings

There are two distinct types of galvanised pipe fittings available on the market: internal fit fittings, and external fit fittings. Both can be tightened using an allen/hex key, but vary slightly in their usage.

External fit pipe fittings are suitable for use on most projects, but are not compliant with building codes for staircases, barriers and balustrades installed in commercial settings. For that reason, a small range of internal fit galvanised fittings have been developed for exactly this purpose. You can find this range of galvanised disability fittings for commercial handrail installations on our online store.

Some customers who are building monkey bars and other play equipment have also shown interest in this range of fittings, as they are less obtrusive than the external fit varieties.

How to connect and install Galvanised pipe clamp fittings

To connect and install galvanised pipe clamp fittings, you will need the following:

  • A length (or two) of galvanised tube.
    Galvanised tube is available through our online store in 27mm, 34mm, 42mm, 48mm and 60mm OD.
  • The fittings
    Also available through our online store in 27mm34mm42mm48mm and 60mm ranges.
  • An allen key

Once you have all of your materials, follow these three simple steps:

  1. Cut the galvanised tube to the desired length.
  2. Assemble the fittings on the ends of the tube.
  3. Use the allen key to tighten the fittings.

It really is that easy!

If you’re looking for some additional tips and tricks, check out some of our recommendations below:

  • In situations where there will be some vibration of the fittings (such as if they are installed on vehicles etc.), we recommend spot welding over the hex fitting to ensure that it does not move/loosen over time.
  • Be sure not to overtighten the fitting, as this may cause damage to the thread or tube.

With these tips in mind, you can easily connect and install galvanised pipe clamp fittings.
