THE IMPROVED IN‑LINE FIGURE 225 QUICK OPENING CLOSURE
ADVANCED DESIGN. EASIER OPERATION.
The new and improved In-Line Figure 225 Quick Opening Closure allows for accurate alignment of the cap to the hub threads, reducing wear and galling. The new davit arm design allows the cap to swing clear of the hub, permitting easy access to thoroughly clean threads before engagement. And, the improved Figure 225 uses a Cap Pin Nut that is fully adjustable for quick and easy adjustments in the field.
In-Line’s welding services save you time and money, delivering a choice of configurations: Closure only; Closure welded to a flange; Closure welded to an elbow and flange. We also offer third party NDE services making your closure purchase ready to install when you are.
