DIN 909:2020 Hex Head Pipe Plug

DIN 909:2020 Hex Head Pipe Plug is characterized by a hex head pipe plug design and is intended for pipe openings needing external wrench operation, convenient service removal, and reliable plugging.

The hex head handles higher installation and removal torque, making it practical for field service or frequently maintained ports; the threaded connection can be used with suitable sealing media. In assembly, the design helps reduce supporting operations, improve positioning consistency, and maintain good interchangeability in repeated production or field service.

Typical applications include oil tanks, pumps and valves, machinery housings, hydraulic lines, drain holes, and inspection ports. The product can be configured with thread form, sealing washer, material, and surface finish to suit indoor, outdoor, light-load, vibration-exposed, or export supply conditions.
