  • Half nipples feature one fixed flange (either tapped or through-hole bolt holes)
  • Full nipples feature one fixed and one rotatable flange (through-hole bolt holes)
  • Conical and straight reducer nipples adapt two different flange sizes
  • Common lengths and tube diameters listed; contact us with your specific requirements
