The LockNLube Hose Swivels are built to withstand up to 10,000 PSI so that you can use them with any grease gun - battery, pneumatic, or hand-pump. Our reinforced design also stands up to lateral pressures that get put on a grease gun hose, not just the pressure of the grease moving through it. The 1/8" NPT connections are standard for all grease hoses in North America.
