ASTM SCH40 & SCH80 PVC-U/C Double Male Threaded Nipple

Key Features

• ASTM SCH40/SCH80 compliant: meets ASTM wall thickness standards.
• Double male threads: standard ASTM male threads on both ends for connecting two female-threaded components.
• All-plastic construction: corrosion resistant, non-rusting, long service life.
• Simple structure: easy installation with PTFE tape and tightening.

Manufacturing Process

Injection molded from PVC-U/C; male threads on both ends formed directly during molding or machined afterwards. High thread dimensional accuracy conforming to ASTM thread standards.

Critical Process Parameters

• Male thread dimensional accuracy and form conform to ASTM standards.
• Coaxiality control of both threads.
• Thread surface finish.

Raw Material Characteristics

• Material Composition: PVC-U or PVC-C, conforming to ASTM D1784.
• Material Properties: PVC-U suitable ≤60°C; PVC-C suitable ≤93°C.
• SCH40/SCH80 wall thickness options available.
• All-plastic material chemical resistant.

Typical Applications

• Connection between two female-threaded valves in ASTM chemical piping.
• Extension or transition between female-threaded fittings.
• Connection between female-threaded equipment ports.

Application Scenarios

• Connection between two female-threaded fittings in ASTM industrial piping.
