Frequently Asked Questions

Q1: What is the difference between NPT and BSP threads? NPT (National Pipe Taper): American standard per ASME B1.20.1, tapered threads 1:16 (3/4″ per foot), 60-degree angle, sizes 1/8″ to 4″ NPT, threads seal mechanically with PTFE tape or sealant, dominant in USA/Canada/Mexico. BSP (British Standard Pipe): British/European standard, BSPP parallel threads G1/8″ to G4″ per ISO 228, 55-degree Whitworth angle, seal with gasket on face not threads, BSPT tapered threads R1/8″ to R4″ per ISO 7, seal like NPT but different taper and angle. NOT INTERCHANGEABLE: Although similar sizes (1/2″ NPT vs. G1/2″), different thread angles and taper prevent compatibility, attempting to mate NPT and BSP causes leaks and thread damage. Use appropriate thread type for your region and equipment.

Q2: Do I need DZR brass or lead-free brass for my plumbing application? DZR Brass (CW602N): Contains 1.6-2.5% lead, dezincification-resistant for hot water >60°C, essential for: hot water distribution, water heaters, recirculation systems, European installations (mandatory many countries per EN standards), 20-40 year service life versus 5-15 years standard brass in hot water. Lead-Free Brass: <0.25% lead per NSF/ANSI 61, required for: North American drinking water systems (USA/Canada EPA mandate since 2014), potable water contact, food processing, water treatment plants. Standard Brass: Adequate for: cold water only, compressed air, non-potable water, industrial fluids, natural gas (check local codes). Recommendation: Hot water systems need DZR brass (Europe) or lead-free DZR (USA/Canada), cold potable water needs lead-free (North America) or can use DZR brass (Europe), industrial compressed air can use standard brass economically.

Q3: What pressure ratings are available for brass fittings? Class 125 (150 PSI): Light-duty fittings, residential plumbing, low-pressure compressed air, typical working pressure 100-125 PSI at room temperature, sizes typically 1/2″ to 4″. Class 250 (300 PSI): Heavy-duty fittings, commercial and industrial plumbing, standard compressed air systems 90-150 PSI, hydraulic applications up to 200 PSI, sizes 1/8″ to 4″, most common for industrial applications. High-Pressure (600 PSI+): Barstock fittings CNC machined from solid brass, hydraulic systems 200-600 PSI, thick-wall construction, sizes 1/8″ to 2″. Derating with Temperature: Pressure ratings decrease with temperature, 300 PSI at 20°C may derate to 200 PSI at 100°C, consult pressure-temperature charts. Safety Factor: Include 2-3× safety factor for water hammer, pressure surges, thermal expansion.
