Gaskets

For Permananent Sealing use the SELCO SEAL. Made in the USA this brand of seal has been used for many years to very great effect. With the SELCO seal you can virtually seal it and forget it SELCO SEAL gaskets are fire safe and prevent blowouts (tested at >5000psi on #2500 flanges). They have excellent tightness characteristics and offer easy installation with no handling losses. The gaskets use binder less flexible graphite and there is no loss of seal under wide fluctuations of temperature and pressure. They offer a permanent seal so there is only need to replace them at maintenance turn rounds. SELCO SEAL gaskets meet or exceed all current EPA fugitive emission requirements.
SELCO SEAL self-locating gaskets are easy to install and offer great savings to systems requiring gaskets in a variety of different pressure ratings. The self-locating version of the seal is shown here in position with 150psi flange on the left and a 2500psi flange on the right. The same seal fits all pressure ratings from 150lb through 2500lb.
As flanges are closed by tightening bolts, the walls of the channel are reformed until the Graphoseal gland bears the full closing pressure and tilts the channel entirely. The lamping force transfers to the seating element, exerts a unit pressure far greater than that of an ordinary gasket. The steel walls of the channel thus lock in the seal and give additional protection from oxidation, corrosion and blowout.
