H-17256
Mueller® Line Stopper Fitting Welding Type - 720 PSIG
Catalog number: H-17256
Specifications:
- Sizes – 3", 4" x 3"**, 4", 6", 8"
- For use on steel pipe only
- O-ring sealed steel (ASTM A216 WCB) Completion Plug with equalizing valve
- Flange, Completion Cap, fitting top and bottom halves are forged steel (ASTM A105)
- Class 300 flange complies with dimensional requirements of ANSI B16.5
- 720 psig*** (4964 kPa) maximum working pressure at 100F (38C)
***This is the maximum pressure of the fitting installed in the line at 100F for Class Locations 1, 2, 3 and 4 as defined in D.O.T./CFR TITLE 49 PART 192. It may be necessary to reduce the line pressure during the drilling, stopping or plugging operations to the maximum working pressure of the machine or its attachments.
