AN to BSP Adapter, AN4 to AN12 Male to 1/8" to 3/4" BSPP Male, Straight

Plenty of pumps, filters, coolers and tanks fitted in Australia use British BSP threads, not NPT. These adapters screw into a BSP port and give you a clean AN male flare to run braided hose from.

• AN male flare one end, BSPP (parallel BSP) male the other
• Twelve sizes from AN4 to 1/8" BSP up to AN12 to 3/4" BSP
• Aluminium, black anodised
• Seal the BSP end with a bonded washer or O-ring, as parallel threads do not seal on the thread

Frequently asked questions

What is the difference between BSP and NPT?
Different thread angle and pitch on most sizes. They can feel like they start, but they will not seal. Measure the port and count the threads per inch before ordering.

BSPP or BSPT?
BSPP is parallel and seals with a washer or O-ring. BSPT is tapered and seals on the thread. These adapters are BSPP.

Will it suit my pump, filter or oil cooler?
Many pumps, filters and coolers sold here use BSP ports. Check the port size and message us if unsure.
