BSPT tapered threads require PTFE tape or anaerobic thread sealant (e.g., Loctite 577) to achieve a leak-free seal. Apply 2–3 wraps of PTFE tape in the direction of thread rotation, starting from the second thread. Do not cover the first thread — this prevents tape fragments from entering the pneumatic circuit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"How many turns should I tighten a BSPT fitting?\"\u003c\/em\u003e — Hand-tight plus 2–3 turns with a wrench for 1\/4” and 3\/8” fittings; 1.5–2 turns for 1\/2” and larger. Over-tightening splits the female port (especially in aluminum or plastic bodies). Under-tightening causes leaks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Can I reuse BSPT fittings?\"\u003c\/em\u003e — Yes, multiple times. Remove old PTFE tape completely before reassembly and apply fresh tape. Inspect threads for damage — crossed or galled threads must be replaced.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"What is the difference between BSPT and NPT?\"\u003c\/em\u003e — Both are tapered pipe threads but with different thread angles: BSPT = 55° (Whitworth form); NPT = 60° (UN form). They are NOT interchangeable — cross-mating causes leaks and thread damage. BSPT is standard in UK, Europe, and Asia; NPT is standard in North America.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n
