Designed to protect threaded port openings during storage, handling, and transit, this tapered plug fits 3/4 NPT threaded connections. Constructed from polyethylene, it resists moisture, mild chemicals, and physical contact that could damage exposed threads or allow contamination to enter open ports.
The Polyethylene 3/4 NPT Tapered Protective cap is a practical choice for hydraulic components, fittings, and equipment with 3/4 NPT ports that require thread protection before installation. The tapered profile allows it to seat securely without tools, making it straightforward to apply and remove across a range of port configurations.
