Adapter nuts are essential components used to securely fasten and connect fittings in fluid power systems. Our selection includes tube nuts, lock nuts, and bulkhead nuts, each designed for specific applications. Tube nuts are typically used to hold tubes in place and create a tight, leak-proof seal when paired with other fittings. Lock nuts provide extra security by preventing the loosening of connections over time, while bulkhead nuts are used to mount fittings through walls or panels, ensuring a secure connection. Available in a variety of materials and sizes, adapter nuts are crucial for ensuring the integrity and reliability of hydraulic and pneumatic systems.
