REDUCING ADAPTOR - NPT X BSPT
REDUCING ADAPTOR - NPT X BSPT
The Reducing Adaptor – NPT x BSPT is a high-quality threaded fitting designed to connect two components with different thread standards, NPT (National Pipe Taper) and BSPT (British Standard Pipe Taper), with varying sizes. This adaptor features NPT male threads on one end and BSPT male threads on the other, with one end being larger and the other smaller, allowing for size reduction between the two different thread standards while maintaining a secure, leak-tight connection. Manufactured from durable, corrosion-resistant materials such as Stainless Steel, Brass, Duplex, Monel, and Hastelloy, the Reducing Adaptor – NPT x BSPT is ideal for applications where both size reduction and thread standard transition are required. It is commonly used in industries such as oil & gas, chemical processing, pneumatic systems, and fluid handling, where both NPT and BSPT components need to be connected in high-pressure or chemically aggressive environments.
- Thread Type: NPT male x BSPT male (National Pipe Taper to British Standard Pipe Taper)
- Reducing Design: Connects components with different thread sizes and standards
- Material Options: Stainless Steel, Brass, Duplex, Monel, Hastelloy
- Size Range: 1/8” to 2” (Imperial) / 3mm to 50mm (Metric)
- Precision-Machined Threads: Ensure leak-tight connections between NPT and BSPT components
- Corrosion, pressure, and temperature-resistant materials
- Eliminates the need for multiple fittings by providing a single solution to connect components with different thread sizes and standards
- Ensures secure, leak-tight connections, even under high-pressure or high-temperature conditions
- Corrosion-resistant materials ensure long-lasting durability and reliability in harsh environments
- Hexagonal body design simplifies tightening and installation using standard wrenches
- Ideal for industries that require transitioning between NPT and BSPT, such as oil & gas, chemical processing, and fluid handling systems
- Reduces the complexity of transitioning between thread types and sizes, saving time and installation costs
