AdaptorMount M22x1.5 Stainless Steel 316 Plug Fitting with Copper Washer | Slim Round Allen Key Head

Meet the AdaptorMount M22 x 1.5 stainless steel threaded plug fitting—a durable, precision-made solution for sealing metric ports in hydraulic, fluid, and industrial systems. Crafted from 316 stainless steel, it offers robust corrosion resistance and long-term reliability in environments that see moisture, chemicals, and heat. The slim round head with an internal Allen key drive enables a clean, low-profile installation where space is tight, helping you maintain clean lines and unobstructed access to nearby components.

Key features blend precision with practical design to support consistent sealing and easy maintenance. The CNC-machined M22 x 1.5 straight thread ensures a dependable fit across compatible openings, reducing guesswork during assembly. The included solid copper sealing washer stands up to thermal cycling, helping maintain a leak-free seal across temperature fluctuations without cracking or deformation. Together, these elements translate to predictable performance in routine maintenance and challenging service conditions.

What this plug is designed to seal

This threaded plug is intended for closing threaded openings in hydraulic equipment, tanks, manifolds, pipe fittings, and fluid-handling components. It provides a durable, metric-threaded closure that stands up to high-moisture environments and demanding workloads.

• 316 stainless steel construction delivers corrosion resistance in challenging environments.
• Precision CNC threads yield a consistent, snug fit for reliable sealing.
• Slim round Allen head supports flush installation in tight or restricted-clearance spaces.
• Includes copper washer to enhance sealing under temperature variation.
• Suitable for equipment such as hydraulic systems, tanks, manifolds, and piping assemblies.

Real-world use scenarios

In a compact hydraulic cabinet, the low-profile head minimizes obstruction around valves and sensors. In a chemical or high-humidity setting, the corrosion resistance helps protect the interface over time. When a system undergoes rapid temperature cycling, the copper washer maintains a dependable seal without deformation, reducing maintenance downtime.

• Use in hydraulic lines and reservoirs where metric ports require a sealed closure.
• Ideal for tanks and manifolds that demand a rugged, long-lasting plug.
