Imperial ABS Plain to Threaded Pipe Fittings FAQ

Below you'll find answers to the most common questions about our Imperial ABS Plain to Threaded Pipe Fittings collection. If you need further guidance on selecting the right fitting for your application, our technical team is always happy to help.

What are Imperial ABS plain to threaded pipe fittings used for?

These fittings allow you to transition from a plain (solvent-weld) ABS pipe connection to a BSP threaded connection within the same system. They are commonly used in industrial processing, water treatment, mechanical services, and chemical handling applications where a mix of jointing methods is required.

What sizes of Imperial ABS plain to threaded fittings do you stock?

We carry a range of imperial sizes to suit common ABS pipework configurations. For the full list of available sizes and fitting types, please browse the collection page or contact our team, who can confirm stock and advise on the correct size for your project.

Are these fittings compatible with standard BSP threads?

Yes. The threaded ends on these fittings are manufactured to British Standard Pipe (BSP) thread specifications, so they connect directly with standard BSP threaded components such as valves, unions, and other pipeline accessories.

What chemicals and fluids can Imperial ABS fittings handle?

ABS (Acrylonitrile Butadiene Styrene) offers good resistance to a wide range of chemicals, including many acids, alkalis, and aqueous solutions. However, chemical compatibility depends on concentration, temperature, and pressure. We recommend checking the manufacturer's chemical resistance chart or speaking with our technical team before specifying fittings for aggressive media.

What pressure ratings apply to these ABS fittings?

Pressure ratings vary depending on the fitting size, type, and operating temperature. As temperature increases, the maximum working pressure decreases. Specific pressure data is available on the relevant product pages, and our team can help you verify that a fitting meets your system requirements.

How are the plain ends of these fittings joined to ABS pipe?

The plain (socket) ends are joined using a solvent cement specifically formulated for ABS. It is important to use the correct ABS solvent cement rather than a PVC or universal adhesive, as this ensures a reliable, permanent bond. Surfaces should be clean, dry, and lightly abraded before cementing.

Can I use PTFE tape on the threaded connections?

Yes, PTFE thread seal tape is recommended on the BSP threaded connections to ensure a leak-free joint. Wrap the tape in the direction of the thread (clockwise when viewed from the end) and avoid over-tightening, as excessive force can crack or damage plastic threads.

Do you offer trade or bulk pricing on these fittings?

We offer competitive pricing across our entire range, and stage payment options are available for larger orders. If you are purchasing in volume or placing a project-specific order, get in touch with our sales team to discuss pricing and availability.

How much does delivery cost, and how quickly will my order arrive?

Call or email us with your pipe size, thread specification, and application details, and we will recommend the correct fitting. We would rather spend time getting the specification right upfront than have you receive the wrong part.
