The 2-1/2" - 11 BSPP Tap is designed for cutting precise British Standard Pipe Parallel (BSPP) threads, ensuring accurate and consistent results. Made from high-quality, durable materials, it is ideal for use on various metals and plastics. This tap is perfect for creating mechanical, non-sealing connections in plumbing, pneumatic, and hydraulic systems. Its precision-ground design ensures smooth threading, while the parallel thread profile provides a tight, secure fit when used with washers or O-rings. Suitable for both professional and DIY applications, it offers long-lasting performance and reliable results.
Differences Between British Taps
Thread Form and Angle:
- ⦿ All use a 55-degree thread angle with rounded crests and roots.
Pitch:
- ⦿ BSF: Finer pitch (threads closer together) than BSW.
- ⦿ BSW: Coarser pitch than BSF.
- ⦿ BSPP & BSPT: Pitch defined by the standard, similar to other Whitworth forms but adapted for pipe fittings.
Application:
- ⦿ BSF: Precision applications needing fine threads.
- ⦿ BSW: General-purpose mechanical applications.
- ⦿ BSPP: Pipe fittings requiring a parallel thread and a sealing washer.
- ⦿ BSPT: Pipe fittings creating a pressure-tight joint via tapering threads.
Sealing:
- ⦿ BSPP: Requires a gasket or O-ring for sealing.
- ⦿ BSPT: Seals through tapered threads, often with sealant.
Practical Example
- ⦿ BSF Tap: Used for threading a precision-engineered component requiring fine threads.
- ⦿ BSPP Tap: Used in a hydraulic system where pipe connections need a leak-proof joint with a washer.
- ⦿ BSPT Tap: Used in gas piping where a tapered thread ensures a pressure-tight connection.
- ⦿ BSW Tap: Used for bolting together parts of a machine where a standard thread is sufficient.
