2 1/2″ Red Plastic FDC Plug NH Expansion Plug Male Thread 3.06″ OD

Description

Product Overview

The 2 1/2″ red plastic FDC plug (NH) is engineered as a high‑performance expansion plug for a wide range of hydraulic and pneumatic applications. Constructed from durable engineering‑grade plastic, the plug offers resistance to corrosion, chemical exposure, and temperature fluctuations commonly encountered in industrial environments. The male side features a 2 1/2 inch NH/NST thread with an outside diameter of 3.06 inches, ensuring a secure, leak‑free connection to compatible female fittings. Designed with a chain‑ready feature, the plug can be easily attached to a chain for rapid deployment in field installations, reducing setup time and minimizing the need for additional hardware. The compact package dimensions of 6.38 x 4.33 x 2.48 inches and a lightweight mass of 4.09 ounces make it convenient for inventory storage and transport. Since its launch on January 12, 2021, the product has earned a five‑star rating from customers, reflecting its reliability and ease of use. This plug is not discontinued by the manufacturer, guaranteeing ongoing availability for maintenance and replacement projects.

Usage

Designed for both new installations and retrofit projects, the plug excels in environments where quick, secure sealing is essential. It is ideal for connecting hydraulic lines in machinery, pneumatic control circuits, and fluid transfer systems where space constraints demand a compact yet robust solution. The red color provides visual identification, helping technicians quickly locate the component during assembly or inspection. Because the plug is made from plastic, it eliminates the risk of galvanic corrosion when paired with metal fittings, extending the service life of the entire system. The chain‑ready capability allows the plug to be suspended from a chain or rope, facilitating installation in hard‑to‑reach locations such as overhead pipelines, confined engine bays, or outdoor rigs. Its lightweight nature reduces the load on supporting structures, making it suitable for mobile equipment, agricultural machinery, and construction tools that experience frequent vibration and movement.

FAQ

What types of fluids can this plug handle?

The plug is suitable for most hydraulic oils, water‑based fluids, and pneumatic air streams. Its plastic material is compatible with typical industrial fluids, but users should verify chemical compatibility for highly aggressive solvents.

Can the plug be used with metal female fittings?

Yes. The plastic male thread is designed to mate with standard metal female NH/NST fittings. The combination avoids galvanic corrosion while maintaining a secure seal.

Is the plug reusable after removal?

While the plug can be removed and reinstalled, it is recommended to inspect the threads for wear before reuse. For critical applications, replacing the plug ensures optimal performance.

How does the chain‑ready feature work?

The plug includes a built‑in loop that accepts a standard chain or rope. This allows technicians to suspend the plug during installation, simplifying alignment and reducing the need for additional lifting tools.

What warranty does the product carry?

We offer a one‑year limited warranty covering material defects and manufacturing errors. If the plug fails under normal operating conditions within this period, we will replace it at no cost.
