WHAT THREAD IS ON 1/2" POLY PIPE
AI Overview
The thread on a 1/2 inch poly pipe is BSP 1/2 in, which is also known as 15 mm or DN15. These terms can be used interchangeably in plumbing catalogs.
do half in poly pipe fittings have straight or tapered threads
AI Overview
Half inch poly pipe fittings typically have tapered threads; most commonly using a "BSPT" (British Standard Pipe Tapered) thread type, which means the threads gradually get smaller as they extend along the fitting, creating a tighter seal when screwed together.
Key points about poly pipe fittings and threads:
Tapered for better seal:
The tapered design allows for a more secure connection by compressing the threads as they are tightened, ensuring a watertight seal.
Thread type:
Most commonly, poly pipe fittings use BSPT threads, which are considered a standard for plumbing applications.
Straight threads exist but are less common:
While some poly pipe fittings might have "BSPP" (British Standard Pipe Parallel) straight threads, these are generally less common due to the sealing benefits of a tapered thread.
Are BSP and BSPT the same?
No, BSP and BSPT are not the same. BSP stands for British Standard Pipe, while BSPT stands for British Standard Pipe Tapered. The main difference between the two is the shape of the thread.
