Loc-Line 41754 1/4″ BSPT Pipe Plug – Pack of 20

About This Product

The Loc-Line 41754 1/4″ BSPT Pipe Plug is a convenient, cost-effective solution for closing unused threaded ports in compatible fluid and air distribution systems. Manufactured for use with Loc-Line components, these compact pipe plugs are particularly useful in modular manifolds, industrial coolant systems, and custom fluid-routing applications.

Designed with 1/4-inch BSPT (British Standard Pipe Taper) threads, each plug provides a threaded closure for compatible female ports, helping prevent unwanted fluid or air discharge from unused connections.

The Loc-Line 41754 plugs are specifically used in the manufacturer’s Magnetic Manifold Kits, including part numbers 40400, 40463, and 40480. These systems allow machinists and technicians to configure multiple coolant or air outlets for industrial applications.

When a manifold has more ports than an application requires, these plugs can close the unused outlets without requiring additional tubing or nozzle assemblies.

The pack of 20 offers a practical quantity for workshops, manufacturing facilities, maintenance departments, and anyone assembling or modifying multiple fluid distribution systems.

Unlike Loc-Line’s modular hose end caps, these pipe plugs are designed to fit compatible threaded ports. They are not intended to snap onto the ends of standard Loc-Line hose segments.

Whether you’re maintaining an existing manifold, building a custom coolant distribution system, or keeping spare fittings available for future modifications, the Loc-Line 41754 provides a simple way to manage unused threaded connections.

Features:

• Genuine Loc-Line component manufactured for compatible fluid distribution systems.
• Manufacturer part number 41754 for straightforward identification and reordering.
• Pack of 20 pipe plugs provides an economical bulk quantity.
• 1/4-inch BSPT male threads designed for compatible tapered female pipe-thread connections.
• Threaded port closure helps block unused openings in compatible manifolds.
• Designed for Loc-Line Magnetic Manifold Kits including models 40400, 40463, and 40480.
• Useful for industrial coolant systems requiring unused outlet ports to be closed.
• Compatible with suitable air distribution applications when operating specifications allow.
• Convenient for manifold reconfiguration when adding or removing coolant outlets.
• Compact fitting design minimizes unnecessary protrusion from compatible connections.
• Practical maintenance accessory for machine shops and manufacturing facilities.
• Bulk packaging helps keep replacement plugs available.
• Useful for custom fluid-routing projects where compatible BSPT threaded closures are needed.
• No moving parts for simple installation and routine maintenance.

Key Benefits

Close Unused Manifold Ports

The Loc-Line 41754 plugs allow unused threaded openings in compatible manifolds to be closed.

This helps users configure their coolant or air distribution systems around the number of outlets actually needed.

Designed for Loc-Line Magnetic Manifolds

These plugs are identified by Loc-Line for use with its magnetic manifold products.

They are particularly useful for shops that periodically change coolant delivery configurations to accommodate different machining operations.

Convenient 20-Piece Package

The bulk pack provides enough plugs for multiple manifold assemblies, equipment upgrades, or replacement inventory.

Simple Threaded Installation

The threaded design allows installation into appropriately sized and threaded female ports without additional modular hose components.

Versatile Industrial Applications

In addition to Loc-Line magnetic manifolds, the plugs may be useful in other compatible fluid or air systems, provided thread compatibility, material compatibility, and operating limits are verified.

Recommended Applications

Machine-Tool Coolant Manifolds

Close unused ports in compatible coolant distribution manifolds used for CNC machining, milling, drilling, and other operations.

Loc-Line Magnetic Manifold Kits

Suitable for the manufacturer’s compatible magnetic manifold products, including:

• Loc-Line 40400 – Magnetic Base Manifold
• Loc-Line 40463 – Magnetic Base Manifold Kit
• Loc-Line 40480 – Magnetic Base Manifold Super Kit

Industrial Air Distribution

Use in compatible air distribution systems where a 1/4-inch BSPT closure is required and the system’s operating conditions are appropriate.

Maintenance and Repair

Keep replacement pipe plugs available for equipment servicing, manifold reconfiguration, and repairs.

Custom Fluid-Routing Assemblies

Useful in custom manifold assemblies that require a compatible 1/4-inch BSPT threaded plug.

Installation and Usage Instructions

1. Verify thread compatibility: Confirm that the receiving port accepts a 1/4-inch BSPT male pipe plug.
2. Depressurize the system: Shut off fluid or air flow and relieve pressure before removing or installing fittings.
3. Inspect the threaded opening: Check for contamination, damaged threads, or debris.
4. Prepare the connection: Follow the manifold or equipment manufacturer’s recommendations regarding thread sealant and installation.
5. Start threading by hand: Carefully engage the plug to avoid cross-threading.
6. Tighten appropriately: Use a suitable installation method without overtightening or damaging the plug or receiving port.
7. Restore system operation: Reintroduce pressure gradually.
8. Inspect for leaks: Check the plug connection before returning the equipment to normal service.

Important: BSPT and NPT are different pipe-thread standards. Do not assume that a 1/4-inch BSPT plug will seal correctly in a 1/4-inch NPT port.

Magnetic manifolds, hose segments, coolant nozzles, and additional fittings are sold separately unless otherwise specified.

Important Product Information

The Loc-Line 41754 is a threaded pipe plug, not a Loc-Line modular hose end cap, nozzle, or flow-control valve.

This product uses 1/4-inch BSPT threads, as specified by the manufacturer. Correct thread identification is important because mixing BSPT with NPT or other incompatible connections can result in leaks or damaged fittings.

The manufacturer identifies the plugs for use in its magnetic manifold systems. Compatibility with other equipment should be confirmed before installation.

The material composition, individual plug pressure rating, and maximum temperature rating were not independently established from the manufacturer’s product listing.

Although Loc-Line products are sometimes adapted for aquarium plumbing, the 41754 is not specifically described as an aquarium-safe component. Its suitability for continuous freshwater or saltwater exposure, submerged installation, or use with aquarium livestock should be verified before use.

Do not use these plugs in pressurized systems beyond the verified ratings of the fittings, manifold, and complete assembly.
