Originally named 7P, Hetman 7.5 is a high viscosity gel lubricant for close-fitting stationary slides. After the discontinuation of Hetman 9, the 7.5 fits the roll of a heavier slide gel that keeps slides firm, but not gunked up. Heavier than number 7, but not as thick as number 8. Will not bunch up in slide tube ends. Adhesive formula protects against corrosion and wear.
