Valve ports are precision-engineered openings in compression chambers that regulate fluid flow, pressure, and direction through controlled valve mechanisms.
Commonly used trade names and technical identifiers for Valve Ports.
This component is used in the following industrial products
The sealed enclosure within an air compressor where air is compressed by reducing its volume.
The internal cavity within a pump head or fluid end where fluid is temporarily contained and pressurized during the pumping cycle.

NPT (National Pipe Thread) ports have a 60° thread angle and taper for sealing, while BSP (British Standard Pipe) ports use 55° threads with parallel (BSPP) or tapered (BSPT) variants. NPT is common in North America, BSP in Europe/Asia.
Use proper thread sealants (PTFE tape, liquid thread sealant), ensure correct torque specifications, verify port surface finish meets requirements, and use compatible sealing washers or O-rings where applicable.
Minor thread damage can be repaired with thread chasers or inserts (Helicoil, Timesert). Severely damaged ports may require welding and re-machining or component replacement.
