Ok quality but needed sealant to fit
"The Type 50 spigot looked to be good quality, but it was a replacement for the Type 30 on my MK4 regulator and it didn't seal when screwed in as tightly as I dared. The threads are the same, but the Type 30 has "bull nosed" end that seemed to seal inside the MK 4 regulator. This new spigot just has a flat surface that doesn't seem to even reach the end to attempt to seal metal on metal. There was no washer or anything supplied. I used some hydraulic sealant on the thread so I guess time will tell if it proves to be reliable."
