Self-Sealing Nuts Engineering

Ordinary nuts and plugs lack adequate seal technology and allow external/internal pressure and contaminants to damage the integrity of the enclosure, and therefore your device. CSFI has engineered a solution to this problem with its exclusive line of self-sealing nuts and seal plugs. We have developed a way to permanently fuse a rubber element to the threads of nuts, thereby lending the nuts excellent sealing capabilities, defense against vibration and convenient reusability. Our seal plugs have been fitted with an O-ring in the groove underneath the head so that, when the seal plug is tightened, the O-ring fills any space beneath the plug creating a complete seal.

CSFI seal nuts are available with various types of sealing material suitable for sealing a wide range of contaminants and they resist most chemicals in different temperature ranges. CSFI seal nuts can also be designed to exhibit excellent weather, ozone and UV resistance. CSFI seal nuts are used in many types of equipment applications such as within the food industry (with our special FDA rubber formula), and many OEM specifications.

CSFI seal nuts can solve numerous problems in applications including:

CSFI seal nuts work against any surface – smooth or irregular, durable or fragile. CSFI seal nuts are more than just a nut because of our unique bonding process which can be used on all types of rubber element material. CSFI seal nuts will perform and function in ways that no regular piece of hardware could perform alone.

For your next project, seal it right with CSFI!
