51804 Loc-Line 3/8″ NPT Connector for 1/2″ ID System, pack of 4

Product details

The "51804 Loc-Line 3/8" NPT Connector for 1/2" ID System, pack of 4" is a plumbing connector designed for use with a Loc-Line style modular tubing setup. It uses 3/8" NPT (National Pipe Thread) so you can join sections of tubing and fittings reliably within an aquarium plumbing run. With a 1/2" ID system designation, it’s intended for applications where the connected line uses a 1/2" inner diameter tubing/bending system. Practically, connectors like this help you build or modify directed flow paths—such as rearranging how water outlets aim—without replacing larger lengths of tubing. Because it’s sold as a multi-pack, you can keep spares on hand for future maintenance or re-plumbing work.

Features:

• Connects parts of a Loc-Line modular plumbing system for aquarium use
• Uses 3/8" NPT threading to help create a secure, threaded joint
• Made for a 1/2" ID system configuration for compatibility with the matching tubing size
• Pack of 4 provides multiple connectors for installation or future adjustments
• NPT is the standard U.S. pipe-thread type, making it easier to match with compatible fittings
