The stainless steel Expansion Flange is technically not in the typical ﬂange family. This purpose designed flange is used to secure tube or piping in wall, ﬂoor and ceiling penetrations.
Commonly used in food or beverage plants, cool stores or any applications where a waterproof hygienic seal is required. The design allows for lineal expansion and contraction of pipework whilst preventing ingress or liquid to penetrate. They help to keep wall penetrations tidy so that nothing can enter into the cavity of the wall or through the wall. Expansion flanges can also stop rodents or insects entering the factory. Expansion flanges are normally screwed or riveted to a wall depending on the material.
When installing expansion flanges, silicon or any sealant can be placed behind the flange to create a watertight seal.
Flange sizes available can accommodate imperial, nominal bore, and metric tube sizes. Non-standard tube diameters can be adapted by adding a custom rubber liner.

Technical Tuesday: What Is Special About Our Thread Sealing Tape?
Thread sealing tape is commonly used in threaded piping applications to seal pipe threads and stop them seizing. Thread tape works as a filler, filling the space between the threads and creating a tight seal which helps to prevent leaks and seizing. Watch Huntley as he discusses our range of thread sealing tape and why it is so special.
Technical Tuesday: Why Are BSP Fittings So Common in New Zealand?
BSP stands for British Standard Pipe and have been adopted internationally as they interconnect and seal pipes and fittings by mating a male thread with a female thread. Watch Huntley as he talks about why they are so common in New Zealand.
Technical Tuesday: What’s the Difference Between EPDM, FKM & HNBR Seals?
EPDM, FKM and HNBR seals are used with our Press-fit system and have different purposes and properties. Watch Huntley as he discusses the difference between each seal to find out what seal might be right for your application.
Technical Tuesday: What are our BSP to Tube Fittings
BSP to tube adapters are used when connecting BSP with imperial tube as normal BSP weld nipples and sockets don’t work nicely with imperial tube. We stock two different types of BSP to tube adapters. A weld nipple adapter, also known as a reducing weld nipple, and a weld socket adapter, that was developed by The Metal Company. Watch Huntley discuss what BSP to tube adapters are.
