Description
Models 555 has a dual-leverage feature which allows it to be operated in either volume or pressure modes. With the link in the volume position, the guns deliver 1 ounce (28.4 grams) of grease in 30 strokes. Shifting the link to the pressure position allows the guns to develop 7500 psi (517 Bar). The guns are capable of 3-way loading: cartridge, suction, and loader pump (requires optional loader fitting 306740 or 322610). Capacity is 16 ounces (454 grams) bulk or 14.5 ounce cartridge. The guns are spring-primed and have an air bleed valve to aid priming. The seals are Buna-N (nitrile) for compatibility with petroleum based greases.
