HOLO-KROME socket pressure plugs are manufactured to suit applications where a pressure tight seal is required with no spiral leakage through the thread form. For maximum sealing taper tapped recommended. Available in Alloy Steel, Stainless Steel and Brass holes are 

DIAMETER RANGE:
  • NPTF 1/16 through 1-1/4 
  • PTF 1/16 through 3/4 
  • Both 3/4 and 7/8 taper plugs used in pneumatic or hydraulic pressure applications. 
  • Alloy Steel products have a minimum hardness of 38HRC 

SIGNIFICANT FEATURES:

•   • Precision-forged deep sockets with smooth, flat walls and controlled corner radius to ensure even distribution of driving torque
•   • Threads are precision rolled to provide smooth fully formed tapered threads for a high pressure seal. Rolled threads improve the sealing action by eliminating spiral machining marks.
•   • Controlled structural grain flow and greater wall thickness provide superior bursting resistance
