Many Rheodyne valves allow the syringe needle to rub across the sealing surfaces a tradeoff in a valve design which avoids the necessity of having to machine small concentric holes. To prolong the lifetime of these injectors, we offer a syringe with a PEEK tip which extends beyond the end of the needle so that only PEEK contacts the valve sealing surfaces.
The basic syringe is our C-160, fitted with a special 2" long 22 gauge needle with a blunt PEEK tip.
Available with fixed or removable needle.
