How can you tell if a hose is male or female?

Male threads are on the outside, like a bolt. Female threads are on the inside, like a nut. The male threads screw into the female threads. This sometimes leads to confusion when dealing with hard brake lines and other rigid tubing.

How are hose tails measured?

Using a ruler or vernier, measure across the outside diameter of a male or hose tailpiece thread or measure the inside diameter of a female thread. If the thread measures 0.5″ it is not a 1/2″ BSP thread.

What size is the female end of a garden hose?

Garden hose connectors usually come in 3/4 or 5/8-inch. It is according to the inside diameter of the hose. Garden hose fittings also vary accordingly and the most popular size is 3/4-inch or 11.5NH. This size is also perfect for commercial purposes.

What is the female end of a pipe?

The bolt is the male connection with the threads on the outside and the nut is the female connection with the threads on the inside. The most basic plumbing fitting is the nut and bolt to join two lengths of pipe.

Is BSP and NPT the same?

NPT and BSP threads are not interchangeable due to the differences in thread forms. NPT threads are pointed in the peaks and valleys, where BSPs are rounded. Most notably, the NPT thread angle is 60 degrees versus the BSP 55-degree angle.

Can you use NPT on BSP?

NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most sizes have a different pitch.

How is BSP fitting measured?

Once you have the thread size, you then need to determine the number of threads per inch to verify that it is a BSP fitting. You can do this by counting the number of thread crests over a 1/4″ length and then multiply this by 4 to get the number of threads per inch.

What are the different types of hose connectors?

There are three key types of hose connector threading:

  • NPT Hose Connectors. A National Pipe Thread Connection features a tapered 60° thread.
  • BSPT Hose Connectors.
  • BSPP Hose Connectors.

What is the thread on a garden hose?

The US standard was defined by NFPA 1963, “Standard for Fire Hose Connections”, then later by ANSI-ASME B1. 20.7, which specifies 1+1⁄16 inches (27 mm) diameter straight (non-tapered) thread with a pitch of 11.5 threads per inch (TPI).
