A Straight Adapter with NPSM (National Pipe Straight Mechanical) to NPTF (National Pipe Tapered Fuel) threads is a specific type of connector used in pipe fittings. NPSM is a straight thread type used in pipe fittings. Unlike NPT (National Pipe Tapered), NPSM threads are straight and do not have a taper. NPSM threads are commonly used in applications where a leak-tight seal is not required, such as in low-pressure systems. NPTF (National Pipe Tapered Fuel): NPTF is a type of tapered thread used in pipe fittings. The threads have a slight taper, which allows for a tighter seal when tightened. NPTF threads are commonly used in applications where a leak-tight seal is required, such as in high-pressure systems or those involving fluids or gases.Attributes:• Manufactured to a precise specification and are built for durability, reliability, and productivity.• The adapter has NPSM threads on one end and NPTF threads on the other end.• Requires the use of sealant or thread tape to create a reliable and leak-tight connection.Applications: A Straight Adapter is used in hydraulic arrangement to connect lubrication pipes.
