Thread: Irrigation pump fittings

Irrigation gear normally uses BSP threads. Standard water and gas threads, and fittings are available at any good hardware store, engineering supplier, or hydraulic fittings outlet. The can be either tapered or parallel threads. Tapered threads seal on the threads and usually require a sealant like old paint, hemp, pipe sealant (I like Loctite Teflon), tape. Parallel threads seal against a shoulder with a gasket or o-ring. I still have most taps and dies in these up to 1" if you can't find them locally.

x2 for Brian Hjelm.

From the few odd jobs I've done lately that involved tapered plumbing threads (mains water, rain water pump, air compressor fittings) I thought it was going to be painful figuring out the threads, but it seems the standard in Australia is BSP or BSPT for all of them. In fact mine were all tapered - BSPT. Pretty safe bet it's one of them IMO. The only other thread I can see it being is the American version NPT, but that would only be if the pump was imported from the USA - purchased online and shipped over here for example. Everything sold on shelves here appears to be BSP/T. I've been sealing BSPT threads with teflon tape.

And obviously all the sizes are in inches.

If so:
Anyone know where I can get brass or steel bungs and couplings (for a reasonable price) to replace the plastic items that came with the pump.

What are you using the pump for?

If I had a dollar for every time someone said that to me.

Try malaga couplers. I got all my brake and fuel hose fittings from them and have been very impressed with the service.

If you click on the product type on the web page it brings up a pdf catalogue of some of their range. I've also been in with random fittings before and they will quite happily size it up, figure out the thread and find something to suite.
