Whether you're routing water lines around a wall stud, connecting irrigation branches, or building a compressed air distribution system, a poorly matched or low-grade fitting can mean leaks, corrosion, and costly rework. These 304 stainless steel 45° equal elbow fittings are built to handle the job cleanly the first time.\u003c\/p\u003e\n\u003cp\u003eEach fitting is a single-piece 45° equal elbow machined from 304 stainless steel, with both a male BSP thread on one end and a female BSP thread on the other — allowing inline connection without additional adapters. Available in BSP sizes from 1\/4\" (DN8) through 2\" (DN50), covering the most common residential and light commercial pipe sizes. All threads conform to BSP (British Standard Pipe) standards.

BSP uses a 55° thread angle while NPT uses a 60° angle, and thread pitches differ across sizes. In most cases, mixing BSP and NPT fittings without a dedicated adapter will result in leaks or cross-threading. Always verify the thread standard of your existing system before ordering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need PTFE tape or thread sealant with these fittings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes, thread sealant is recommended. BSPP (parallel) threads require PTFE tape or a thread sealant compound to achieve a leak-free connection. BSPT (tapered) threads rely partly on the taper for sealing but still benefit from 2–3 wraps of PTFE tape on the male thread.
