Key Features

• ✅ 3/4" BSPT Specification—Confirmed Inner Diameter of 25 mm: This cap is designed for 3/4-inch BSPT (British Standard Pipe Thread) female threads. The actual inner diameter is approximately 25 mm—not 20 mm, nor 1 inch. Quick Check: Measure the inner diameter of your female threaded pipe cap opening. If the diameter is approximately 25 mm, this 3/4“ BSPT pipe cap is suitable. Not Compatible: 3/4” NPT threads, 1/2" BSPT pipes, copper tubing, or standard garden hose threads. Be sure to verify your male thread type.
• Made entirely of PVC—for cold water use only: Crafted from high-quality, non-toxic white PVC. Durable and UV-resistant, suitable for long-term outdoor use (irrigation, sprinkler systems). Temperature limit: 140°F (60°C). For cold water plumbing only—do not use with hot water or steam.
• Applications—Sealing 3/4” BSPT Pipes: Ideal for sealing unused 3/4” BSPT male threaded ends in the following scenarios: sprinkler risers and manifold outlets, drip irrigation main lines, and garden water supply lines (please verify thread compatibility). Note: Not compatible with Rain Bird 1800 Series or most U.S. standard sprinkler heads that use NPT threads. For BSPT-based systems only.
• Installation – Sealing Tape Required: Easy DIY Installation: Wrap 5–8 turns of PTFE sealing tape clockwise around the male thread. Hand-tighten the 3/4" cap, then use pliers to tighten it an additional ¼ turn if necessary. Pro Tip: Do not use pipe grease alone—sealing tape provides a better seal for tapered threads. Check for leaks before burying underground.
• Important Note – Avoid Mismatched Connections: This cap is designed for 3/4“ BSPT male threads (approximately 25 mm inner diameter). Not compatible with: 1/2” BSPT, 3/4" NPT, copper tubing, garden hose threads (GHT), or metric threads. Not suitable for hot water—maximum temperature 140°F. This product comes in a 12-pack. For smaller sizes, please choose our 1/2" BSPT version (internal diameter approx. 20 mm). If in doubt, measure the pipe’s outer diameter or thread pitch.
