What is the industry standard method for the physical connection of the power (220) to the spa's pigtail leads.

The spa does not have terminals but four pigtails (Hot, Hot, Neutral, & Ground). Are wire nuts and tape adequate (does not sound that way to me) or huge insulated crimps (I can't find any in San Antonio that will accommodate 1 x 12ga and 1 x 8 ga). In the past I used a neat insulated metal block that had two hex head screws sunk into the block and it made a nice strong physical connection but over he past 9 years the insulation has begun to discolor and look as if they have heated up and melted a bit.

I need to replace them but need some guidance on what to use.

Thanks,

most installs call for either hard conduit or flexible conduit, our state / local/ national codes are ok with pvc, better check your area also required is a 2 pole gfci 50 amp breaker
within 15 ft. again check your local code, connections various ways altho the insulated ones you mentioned are superb at least for the # 8
