Review on Lumax LX 1214 Grease Springs 16 28 by Cody Cobbs

Product claims 1/8" NPT x 7/16"-28 UNEF upon receipt of hose which I have 100% confirmed to be 1/8" "NPT x 7/16"-20 UNEF Won't flex and work with my Lincoln #1163 grease gun which has a 7/16"-28 thread on the check valve port on the gun. I ordered a second one and hope it works it will arrive right!if that fails i will order the original lincoln hose #1218 but was hoping that lumax is a higher quality hose.the second hose upgrade was wrong too!ordered that one Original Lincoln with 7/16-28 unef The second upgrade received Lincoln #1218 and had the correct 7/16"-28 UNEF hose but a much stiffer hose, unfortunately the Lumax struggled as it was designed for a 10000 psi hose was slightly more flexible.
