$6.00$4.00

Galvanised male-male coupler with rubber seal. Designed for use in 100mm galvanised ducting systems.

The male spigot fits inside galvanised spiral pipe, flexible ducting, and can be used to link lengths of galvanised pipe together. 

This coupler can also be used to fit inside the Clarke mini dust extractor to convert it from bag-collection to venting outdoors. 

We at ZOIC PalaeoTech have put together a range of dust extracting ducting that fits together and is simple to visualise and assemble. We know how difficult it is to work out which fittings work with each other, how many to get of each, whether any couplers are needed, and so we have put together a guide for you.

Other shapes and sizes are available upon request. 


If for whatever reason you are not able to add enough stock to your basket, please contact us! We try to keep a reasonable stockholding here, but it can be difficult to anticipate what people will require. The vast majority of products we can order in extremely quickly. 

The ZOIC PalaeoTech ducting range

Galvanised and flexible ducting are the only suitable options for ducting in the fossil preparation workshop. This is because they are resistant to abrasive dusts and stone dust. It can also be grounded quite easily. Planning is key when designing the dust extraction in your workshop, but hopefully we can help you by making sure that you have what you need from the start! It's important to know what fits with what, and how to attach them. 


Galvanised ducting and its fittings come with one of two 'ends'. The male ends will fit inside the female ends. For instance, on most fittings the ends will be male (e.g. on an elbow) and the ducting itself is female. You can also use couplers to join these together as required. 



Flexible ducting is much more flexible, and will fit on either male or female ends, but will require a hose clamp to secure it in place. Galvanised ducting and fittings require joining with Tecseal solvent sealant, unless there is already a rubber seal in place.
