It always important to correctly understand the BSP standard measurements, as it is very common mistake to judge the thread fittings sizes by their diameter which is not how the BSP standard works. Please check the table below which will help with correct thread reducer fitting choice.
Our selection of thread adaptors includes various BSP sizes such as 3/8", 1/2", 3/4", and 1", ensuring compatibility with a wide range of pipes and fittings. Additionally, these adaptors are available in both chrome and natural colours, allowing you to choose the option that best suits your aesthetic preferences.
One of the standout offerings in this category is the 3/8x1/4 Inch Male x Female Reducing Bush Adapter Thread Reducer, which provides a seamless transition from a 3/8" male thread to a 1/4" female thread. This particular product is perfect for situations where you need to downsize your pipe connection without compromising on quality or durability.
Another popular choice is the 3/8 1/2 3/4 Inch Threaded Bush Male x Female Pipe Fittings Reducer Chrome. This versatile adaptor allows for transitions between different sizes, making it an ideal solution for various plumbing projects.

An example of this is the 3/8" Female x Male BSP x NPT Connector Thread Adaptor UK Thread to American, which provides a seamless transition between these two thread types.

from 1164 reviewsPerfect fit, received as described, good value and quick delivery.
Ordering process is very easy and Item was good value and arrived next day
Fantastic service
Bought this to replace a standard outside tap as I needed a way to lock it off in order to stop little hands flooding the new patio! Works a treat. Simple to install and is good and heavy, as Boris the Blalde says - heavy is good, heavy is reliable. Service was excellent and item was well packaged and arrived quickly. Will definitely purchase from here again.
Item received on time. Kept fully informed. Good quality item. Excellent service. Would recommend this company to anyone. Thank you to plumbing44home.
Was fine. Fast delivery.
Pot cover fits well and looks good. Great service all round.
This is a great quality tap. My old brass screw tap was leaking so I decided to replace it with a ball valve. My wife loves it as it’s so quick to turn on compared to turn after turn with the old one. Good value for money, easy to fit and well recommended.
I used these to reconnect my water softener, after it was temporarily removed for repair. I noticed the "hard water bypass" pressure was better, so and when re-installing I decided the old/original "small-bore" hose might be the cause, and I was correct. Other "big brand" hoses do not have the correct connectors at each end, I needed two female ends with correct thread sizing is these products provided EXACTLY what I needed. My shower pressure is better, BUY 100cm version and the full bore hose is chunky to manipulate and extra length is therefore necessary.
Arrived on time in perfect condition and exactly as described. Perfect.
I needed a plug for a shower but had no idea what it was, so used Google Lens found out, looked on line, saw it in stock at Plumbing4Home, did a quick look up, the price was right ordered and arrived with in48hours I think. Good service and if I need another pluming part will be back.
Excellent service. Quick delivery and great quality. Very happy.
Good service and a good product.
Needed to fit a hopper gully to solve an open pipe problem and this worked well. Very efficient and fast service from this company.
Arrived early, customer delighted, did the job.
Finally a pipe to fit the universal trap to main waste pipe of the house!
