NPT and O-Ring Boss Adapters & Fittings

NPT fittings use tapered threads for sealing and may degrade with repeated use. In contrast, O-Ring Boss fittings are designed for reusable, leak-free connections in high-pressure systems, making them ideal when you need to frequently disassemble and reassemble hydraulic lines.

Thread sizes range from #4 to #20 to accommodate various hydraulic system requirements. Our experienced engineers and salesmen can provide technical support and assistance with product selection to ensure you get the correct fitting for your specific application.
