Thumbnail Filmstrip of FPX-08-08 | 1/2" Hose x 1/2" NPSM Swivel Female Images
A FPX-08-08 1/2" hose x 1/2" NPSM swivel female is a type of hydraulic fitting that consists of two parts: a hose fitting with a 1/2" inside diameter and a female swivel fitting with a 1/2" size and National Pipe Straight Mechanical (NPSM) threads. The NPSM thread is a straight thread with a 60-degree flank angle and is commonly used in low-pressure hydraulic systems. The female swivel fitting has a cone-shaped seat that mates with a corresponding male fitting, providing a reliable seal in low-pressure hydraulic applications. The swivel design allows the fitting to rotate and pivot, making it easier to install.
Questions & Answers
Popular Questions
NPSM (National Pipe Straight Mechanical) and NPT (National Pipe Tapered) are not directly compatible because they have different thread designs. NPSM has straight threads, primarily used for mechanical connections, while NPT has tapered threads, designed for sealing under pressure. To connect them, an adapter or sealing method, such as a gasket or O-ring, is typically required to ensure a leak-proof connection.
NPSM stands for National Pipe Straight Mechanical, which refers to a type of pipe thread used in mechanical applications. Unlike tapered threads, NPSM threads are straight and do not provide a seal on their own; they are typically used in situations where a seal is achieved through other means, such as an O-ring or gasket. These threads are standardized by ANSI/ASME B1.20.1 and are commonly used for mechanical connections where pressure-tight sealing is not required.
To measure an NPSM (National Pipe Straight Mechanical) thread, you need to use a thread gauge specifically designed for NPSM threads to check the pitch and diameter. Ensure that the gauge fits snugly without gaps or overlaps, and use a caliper to measure the outside diameter of the male thread or the inside diameter of the female thread to confirm it matches the specified NPSM dimensions.
Yes, this fitting interchanges with Weatherhead 08U-058. This interchangeability offers flexibility in sourcing and replacement, making it easier to integrate into existing systems or to find replacements in the field. The 1/2 NPSM fitting provides a reliable seal in low-pressure hydraulic applications.
NPSM (National Pipe Straight Mechanical) threads are straight threads that are compatible with NPT (National Pipe Tapered) threads when used with a sealing component like an O-ring or gasket. NPSM threads are typically used in mechanical joints where a seal is achieved through a separate sealing method, not by the threads themselves. Therefore, while NPSM and NPT threads can be used together, the connection requires an additional sealing element to ensure leak-proof performance.
