Why This Adapter
Engineered for Reliability. Built for the Trade.
NPT (National Pipe Taper) and BSPP (British Standard Parallel Pipe) are two of the most widely used thread standards in global industry — yet they are fundamentally incompatible without a precision conversion fitting. This adapter eliminates that incompatibility with a machined steel body that maintains dimensional accuracy across both thread forms.
The corrosion-resistant finish protects against moisture, oils, and workshop contaminants, ensuring long service life even in high-cycle or outdoor environments. Its compact form factor allows installation in confined manifold spaces without sacrificing wrench clearance or torque integrity.
Key Features
| ✓ | Converts 1/4" NPT male to 1/4" BSPP (Rp) female — bridges two of the most common international thread standards |
| ✓ | Heavy-duty steel construction — withstands high-pressure pneumatic and hydraulic operating conditions |
| ✓ | Corrosion-resistant finish — protects against moisture, oils, and workshop contaminants for extended service life |
| ✓ | Secure, leak-resistant threaded connection — precision thread form ensures consistent sealing under pressure |
| ✓ | Compact profile — fits in tight manifold and panel spaces without sacrificing installation access |
| ✓ | Broad application compatibility — suitable for compressed air lines, fluid transfer, hydraulic circuits, and general workshop use |
