Always use appropriate thread sealant (PTFE tape or thread compound rated for your media) and verify compatibility with local codes and system requirements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need thread sealant with these fittings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. BSPP (parallel) threads do not seal on the thread form alone — a sealing washer, O-ring face seal, or PTFE thread tape is typically required for a leak-free connection. We recommend wrapping PTFE tape clockwise (when facing the thread end) 2–3 times around the male thread before assembly.
