Cross Port Plugs, a small and leak-proof solution

The leak-proof Cross Port Plugs are a plugging solution specifically engineered to seal cross port passageways. This configuration is a variant of the original design that set industry standards over 65 years ago. A smooth wall design combined with the field-proven controlled expansion principle creates a permanent, leak-proof seal. Use them without the need for o-rings or sealants.

Installation is simple, reliable, and requires no maintenance. The Cross Port Plugs are constructed from 6Al -4V Titanium. They have been qualified for proof pressures over 20,000 psi and at temperatures up to 400°F. Configurations are available in .250, .281, and .343 inch diameters.

From aircraft to racecar

The Cross Port Plugs are ideal for isolating sections of a fluidic manifold. They are also used to plug deep passageways that are difficult to access with conventional sealing methods. Typical applications are found in down-hole oil drilling, wireline and completion tools and in aircraft. Also the plugs can be used in high performance race cars or anywhere that requires a leak-proof seal. Contact your Engineer to find the right solution for you.
