Overview
NPST pup joints use non-pressure-seal threaded union ends to connect compatible well-service flowline equipment across short, precisely selected spans. Choose this style when a layout needs a 1- or 2-foot standard section or a custom length to establish equipment spacing, bridge an installation gap, or complete a compact pressure-control assembly.
- NPST threaded-end construction for compatible hammer-union flowline equipment
- One- and two-foot standard lengths for compact equipment-spacing requirements
- Custom lengths available when standard sections do not match the layout
- Used for hydraulic fracturing, cementing, well testing, and flowback assemblies
