Frequently Asked Questions
Q1: What is the difference between NPT and BSP threads? NPT (National Pipe Taper): American standard per ASME B1.20.1, 60° thread angle, 1:16 taper, seals on threads with PTFE tape or pipe dope, used in North America. BSP (British Standard Pipe): Two types – BSPT tapered threads (R) similar to NPT but 55° Whitworth angle, seals on threads, BSPP parallel threads (G) seals on gasket/O-ring not threads, used in Europe, Asia, Commonwealth. Not Interchangeable: NPT and BSP threads do not mate properly, different pitch and angle cause leaks, adapters required for mixing systems. Selection: Use NPT for North American installations, BSP for international/European equipment, check equipment specifications before ordering.
Q2: Should I use lead-free brass or DZR brass for my plumbing application? Lead-Free Brass: Required for potable drinking water contact in North America (NSF/ANSI 61 mandatory), <0.25% lead content, complies with Safe Drinking Water Act, required by state laws (California AB1953, Vermont S-152), prevents lead leaching into drinking water, 25-40% cost premium. DZR Brass: Required for hot water systems >60°C in Europe per EN 12165, prevents dezincification corrosion in hot water, 20-40 year service life versus 10-15 years standard brass, mandated in UK, Germany, many European countries, 15-25% cost premium. Recommendation: North America potable water = lead-free brass, Europe hot water = DZR brass (lead-free versions available combining both), non-potable applications (compressed air, gas, industrial fluids) = standard brass economical.
Q3: What pressure ratings are available for brass pipe fittings? Class 125 (150 PSI): Low-pressure applications, residential plumbing, light commercial, drainage fittings, maximum working pressure 125 PSI water at 20°C. Class 250 (300 PSI): High-pressure applications, commercial/industrial plumbing, compressed air up to 200 PSI, hydraulic systems, maximum working pressure 250 PSI water at 20°C. Special High-Pressure: Up to 600 PSI for specialized hydraulic fittings, thick-wall construction, limited size range typically ≤1″. Derating: Pressure ratings decrease with temperature (300 PSI at 20°C becomes ~200 PSI at 93°C for brass), consult pressure-temperature charts. Gas Applications: Natural gas systems typically 125 PSI rating (NFPA 54), LPG 250 PSI, compressed air 150-300 PSI depending on application.
Q4: Can brass fittings be used for natural gas and propane? Yes, brass fittings widely used for natural gas and LPG/propane distribution. Requirements: Threaded NPT fittings per NFPA 54 (National Fuel Gas Code), brass or steel fittings approved for gas service, forged brass C37700 preferred for strength, pressure ratings 125 PSI for natural gas (typically <0.5 PSI residential, 2-5 PSI commercial), 250 PSI for LPG propane. Flare Fittings: Brass flare fittings commonly used for flexible gas connections (appliances, equipment), 45-degree flare connections, SAE or propane flare configurations. Thread Sealant: Use gas-rated thread sealant (yellow PTFE tape for gas, pipe dope rated for gas service), never use white PTFE tape or standard pipe dope on gas.
