The Rectus Series 26 (brass material) from Parker has been upgraded to a technically improved version which will start to replace the current design as stocks are replenished.
This new design has a lower connecting/ disconnecting force which allows the user
to operate with less effort. This is made possible by using a spring with an optimised spring force which also maintains the vacuum stability of the current design.
A further improvement is the placement of the O-ring, which is now seated in a chamber for better protection against possible damage from the front face of the plug, resulting in an extended lifespan.
This change affects all Series 26 in brass (single shut off (KA), double shut off (KB) and straight through versions (KF), including all special versions (all O-ring variants and surface treatments).
The Series 26KE self venting version is not affected by this change.
These technical improvements have no effect on form, fit and function.
