ORS-to-NPTF steel hydraulic hose adapters are commonly used in high-pressure hydraulic applications to connect compatible hydraulic hoses to pipe or equipment. They are durable, wear-resistant, and suitable for environments where corrosion is not a concern. They have an ORS (O-Ring Seal) connection on one end and an NPTF (National Pipe Tapered Fuel) connection on the other end. The ORS connection has an O-ring and straight threads that form a tight seal when joined to the opposite gender. The NPTF connection (or dryseal thread) forms a secure seal when mated with the opposite gender. This listing is for each.
