Plugs with External Hex Drive

For Use With:

Solid: Air, Steam, Oil, Water, Natural Gas

Solid with Magnet: Air, Steam, Water, Natural Gas

Specifications Met:

BSPP and Metric with Washer: DIN 910

BSPT: DIN 909

Compact Extreme-Pressure Steel Threaded Pipe Fittings: These fittings are strong enough to handle extreme pressures yet small enough to fit into cramped spaces. They are galvanized and zinc-plated steel, which have better corrosion resistance than plain steel fittings.

NPTF (Dryseal) threads are compatible with NPT threads. BSPP and metric male threads have either a gasket or a washer to prevent leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have either a gasket or a gasket and washer to prevent leaks.

Compact Precision Extreme-Pressure Steel Threaded Pipe Fittings: Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings. They are strong enough to handle extreme pressures yet small enough to fit into cramped spaces. They are made of galvanized steel, which has fair corrosion resistance.

Low-Pressure Iron and Steel Threaded Pipe Fittings: These fittings are used for low-pressure applications in noncorrosive environments.

For Use With:

NPT, BSPP, and Metric: Air, Natural Gas, Oil, Steam, Water

NPTF: Air, Natural Gas, Steam, Water

Pressure Class:

NPT: 150

Specifications Met:

BSPP and Metric: DIN 908

Pipe Nipples and Pipe:

NPT: Use Schedule 40 steel

Compact straight connectors can fit into tight spaces. They are also known as merchant couplings.

Plugs with copper washers form a tight seal to prevent leaks. Also known as a crush washer, the washer compresses and deforms to fill gaps when tightened. Because it loses its shape when compressed, it’s not reusable. Made of copper, the washer resists rust. These plugs meet DIN 908, DIN 909, or DIN 910, international standards for pipe plug dimensions.

NPTF (Dryseal) threads, NPSC (National Pipe Straight Coupling) threads, and NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.

For Use With:

NPT and BSPT: Air, Natural Gas, Oil, Steam, Water

NPTF: Air, Natural Gas, Steam, Water

Pressure Class:

NPT Iron: 125

BSPT Iron: 150

Specifications Met:

Pipe Nipples and Pipe:

NPT and BPST: Use Schedule 40 steel

The features of Plugs with External Flange Hex Drive mainly include dimensional standards, material standards, production process standards, testing standards, and standardized use. 

Dimensional standards: Plugs with an external flange hex drive should be measured according to national or industry standards, including thread diameter, pitch, length, and other parameters. 

Material standard: The material of Plugs with External Flange Hex Drive should meet the specific requirements of strength, hardness, corrosion resistance, etc., usually using carbon steel, Alloy steel, stainless steel, and other materials. 

Production process standard: the production process should be in strict accordance with the relevant process requirements for production and processing, including turning, tapping, heat treatment, surface treatment, and other processes. Processes 

Testing standards: suitable testing equipment and methods should be used to test the pipe thread hexagonal screw plugs to ensure that their dimensional accuracy, surface quality, mechanical properties, and other requirements are in line with the standard. 

Standardized use: In the process of installation and use, it should be tightened according to the torque specified in the standard to avoid quality problems caused by over-tightening or over-loosening. In the process of storage and transportation, attention should also be paid to avoiding moisture, pollution, and other conditions that could affect its use and performance. 

Together, these features ensure the quality of the pipe thread hexagonal screw plugs, improve production efficiency, and are essential for a variety of industrial applications

1. Different application scenarios

Plugs with External Flange Hex Drive are suitable for threaded bores. For example, it can be used in threaded holes in machine parts connections, where it can be used to prevent the entry of dust and debris during maintenance.

Plugs with External Flange Hex Drive are suitable for pipe connections. For example, this plug can connect, tighten, and keep the connection sealed in the cross-hole between a pipe and an accessory.

2. Different methods of use

Plugs with External Flange Hex Drive are threaded and require the plug to be screwed into the threaded bore and then tightened to secure it. Usually, a wrench is used to achieve a high tightening force.

Plugs with External Flange Hex Drive have a tubular connection and require a screw plug to be inserted into the hole in the tubular connection, rotated and plugged, and then secured with a wrench. The connection angle and tightening strength of the pipe and the screw plug need to be paid attention to achieve a good sealing effect.
