The actual inner diameter is approx. 20mm – not 15mm, not 25mm. ✅ How to check: Measure the inside of your female cap or the outside of your male pipe. If your male thread measures about 20mm across the outer diameter, this 1\/2\" BSPT cap is correct. ❌ Will not fit: 1\/2\" NPT threads, 1\/2\" copper pipe, or 3\/4\" sprinkler connections. Please confirm your thread type before ordering.\u003c\/li\u003e\n\u003cli\u003eReliable PVC Material – For Cold Water Only: Made of non-toxic, durable white PVC.

For a leak-proof seal: Wrap 5–8 turns of PTFE sealing tape (or use a rubber sealing ring) around the male threads. Screw the cap on hand-tight + ¼ turn. ⚠️ Do not overtighten – PVC can crack.
