Rated 4 out of 5 by from Soil pipe connector If you want a leak proof connection onto a soil pipe then this is the perfect product. Far better than a boss and strap . Quite pricey but reliable .

Rated 5 out of 5 by from Simple fit Nice and simple piece of kit to fit. Worked a treat with the 57mm hole saw(also purchased from screwfix). Also a lot cheaper than similar kit from well known diy store.

Rated 1 out of 5 by from who writes reviews I'm a McAlpine devotee and really wanted and needed this kit to work but really, unless I'm missing something, it's just not fit for purpose. Been in plumbing trade man and boy, before I'm judged, can only see me trying for a refund as this is useless

Rated 5 out of 5 by from Awesome adapter Once cast iron pipe was drilled you just pop it in tighten it up and jobs a good'n. Would definitely use again!! Has saved removing a cast iron soil stack which let's be honest is not much fun. Can't recommend highly enough.

Rated 4 out of 5 by from Good not Great 57mm hole saw through the pipe and tightened up the boss, I was putting a u bend, dishwasher Waste and sink waste directly into the boss and it seemed a bit flimsy, took it out applied silicon to all the mating faces and around the rubber seal put it back in and tightened again, wrapped a large cable tie around the top and bottom and tightened - boss doesn't move now and no leaks at all.

Rated 3 out of 5 by from Pipe Boss Review The Pipe Boss is well manufactured, but the installation instructions are appalling:- the picture of the fitting tool was so badly drawn that I thought it was missing from the pack (and I'm an engineer and familiar with looking at technical drawings). The last person to purchase it also couldn't figure out how to install it, so had returned it to store after opening the bag. The tool is plastic and has lugs ('ears') on it. Once you understand this, installation is easy. There is no online video regarding installation. The fitting itself is smart, neat and well engineered.

Rated 5 out of 5 by from Pipe boss (mechanical) This is a very good product,however the instructions could be clearer,the fixing tool should be removed from the assembly in the first instance,I thought it was part of the workings and failed to recognise the part for what it was,also the the drawings 2+3 on the instructions have omitted the lugs on the tool,had they been drawn on the part would have been easier to identify,excellent product when I realised how it worked.
