An NPT-M x NPT-M male close nipple pipe fitting is designed to join two female NPT-threaded components with minimal spacing between them. Featuring male NPT threads on both ends with a very short body, close nipples are ideal where compact installations or tight clearances are required.
These fittings are widely used in hydraulic, pneumatic, oil and gas, plumbing, and general industrial systems where a secure, pressure-tight connection is needed without adding unnecessary length. The tapered NPT threads create a reliable, leak-resistant seal when installed with suitable thread sealant.
