Plugs handle high pressure July 1st 2004 Axial Force Only (AFO) plugs from Lee Products are removable, reusable and suitable for high pressure and high temperature use.
They have a floating seal that self-aligns to allow for threaded holes that are not concentric with the through hole. As a result of the plugs two-piece construction, the seal does not rotate during installation, preventing galling of the seat. Since the force is contained in the axial direction, the company says the boss diameter can be smaller compared to other designs of plug.
Standard AFO plugs are made from corrosion-resistant 303 and 15-5 stainless steel and do not require O-rings or sealants. They can withstand pressures to
60 000psi and temperatures to 600F. More articles from Lee Products Ltd: |
