Screw Plugs

The Screw Plug is a precision-engineered sealing component designed to close or block threaded ports in hydraulic, pneumatic, and mechanical systems. Commonly referred to as set screws, blocking plugs, or stoppers, these components are essential for maintaining pressure integrity and preventing fluid or gas leakage in assemblies.

Product Details:

• Thread Standards: Available in M (metric), G (parallel pipe), R (tapered pipe), and NP (American pipe) threads for compatibility with various industrial systems.
• Shapes: Offered in standard and flanged configurations. The flanged design provides enhanced sealing capability and distributes load evenly on the mating surface.
• Head/Mounting Type: Equipped with hex socket or hex socket (through) styles, allowing easy installation and removal using Allen keys or hex tools.

Material Options:

• Steel: Provides strength and reliability for general-purpose mechanical sealing.
• Stainless Steel: Offers superior corrosion resistance for fluid systems, chemical environments, and outdoor applications.
• Plastic: Lightweight and non-corrosive option suitable for low-pressure or non-metallic assemblies.

Sealing Capability: Designed for high integrity in both pressure and vacuum applications, preventing leaks even under variable temperature or vibration.

Surface Finish: Screw Plugs are available with various surface treatments depending on the material and application requirements. Common finishes include trivalent chromate plating, black oxide, and electroless nickel plating, offering enhanced corrosion resistance and durability. Untreated (raw) finishes may also be available for certain models.

Applications: Commonly used in hydraulic manifolds, pneumatic control blocks, oil passages, valve bodies, and gear housings.

This Screw Plug series provides a reliable, space-efficient sealing solution suitable for diverse industrial environments where durability, compatibility, and maintenance ease are critical.
