BSP is not a single thread shape. BSPP is parallel; BSPT is tapered. NPT is also tapered, but that does not make it interchangeable with BSPT. JIC is a different connection system. Confirm the complete connection, not just a familiar abbreviation.
Start by identifying the thread family.
| Family | Thread form | Before ordering |
|---|---|---|
| BSPP | Parallel | Confirm the specified sealing arrangement as well as thread size. |
| BSPT | Tapered | Check the mating connection and manufacturer specification. |
| NPT | Tapered | Do not assume compatibility with a BSPT connection. |
| JIC | Parallel thread | Identify the complete end connection and its mating sealing surfaces. |
Manufacturer guidance distinguishes these tapered and parallel thread families.
Collect the information that narrows the match.
- Any manufacturer marking, part number or connection standard.
- Thread diameter and pitch, measured with suitable tools.
- Whether the thread is male or female, parallel or tapered.
- The shape and condition of the sealing connection.
- The fluid, working pressure, temperature and application.
A clear photograph can start identification. Measurements, a drawing or a physical sample may still be needed to confirm the requirement.
Do not identify a thread by forcing a fit.
Similar-looking connections can have different thread geometry or sealing requirements. Do not use tightening resistance as an identification method. Confirm compatibility against the relevant manufacturer documentation.
This guide is an introduction for product enquiries, not an installation procedure or certification of compatibility. Follow the equipment and component manufacturer’s instructions, and use a qualified technician for hydraulic-system work.
