700008840 - Check Valve, 3/8" x 0.646", 10k psi
This replaces part 700006601 (Thar part number 01377-1), which looked slightly different. The pictures below help identify the two types. When looking at the check valves from the side, the new-style PEEK seals are visible on top and bottom.
Do not confuse this part with part 700006600 (Check Valve, 3/8"Dia, 10k PSI, Cartridge), the check valves for the P-200A pump.
