Concentric Reducer

Because of our international reputation, we stock all of the standard sizes used in the European pipe coupling industry, along with a huge number of sizes used internationally. We also have the capability to produce tailor-made products, designed to meet different customer specifications.


The Advance Couplings product range includes standard sized clamps, ferrules, gaskets, BSP adaptors concentric reducers and eccentric reducers.  All items are part-marked with material certificates supplied as standard.


The Advanced Couplings reducer range comprises of ferrule ended Concentric Reducers, ferrule ended Eccentric Reducers and plain ended Pipe to Tube Reducers.  All concentric reducers are machined from 3.1b certified 316L solid bar and to guarantee the highest possible surface finish, are manufactured to 0.8Ra as standard.  However additional 06Ra and 0.4Ra electro-polishing options are also available.


The Concentric Reducer range is supplied as ferrule-ended as standard to enable the fitting to be easily clamped on to pipe work and quickly removed again.  Easy fitting and removal is important for thorough and efficient cleaning.  Ferrule ended concentric reducers are available in standard dimensions although Advanced Couplings are able to manufacture concentric reducers to meet different customer requirements.


A cleaner, self-draining version of the concentric reducer, Advanced Couplings eccentric reducers are supplied with ferrule ends as standard.  Ferrule ended eccentric reducers are manufactured in standard dimensions although different mating ends can be supplied and manufactured on request.


Plain ended Pipe to Tube Reducers are useful for converting the Schedule Pipe Work which is frequently used in the United States to the OD Tubing more commonly used in Europe and the UK.  Advanced Couplings’ Pipe to Tube Reducers are machined from 3.1b certified 316L solid bar with electro-polishing options available on request.
