I needed to repair my pressure valve as the spring broke and the washer disintegrated.  I was really worried about the pins coming out of the popper, as they are like two legs of a cotter pin poured into the lead top. I stressed finding a acceptable spring & washer and I found what I needed on McMaster-Carr.  As luck would have it, they have a warehouse 20 miles away from my Atlanta Mid-Town apartment and was able to just just pick the parts up!  Super-duper score saving on shipping and being able to visit their warehouse (it is HUGE)!

Anyways, here is a picture of it repaired with the original spring on the far left, then the two springs and the washers.  I did end up snipping 2~3 turns off the 8969T322 spring.

  • I used is the tighter spring and its part number is 8969T322  - 316 Stainless Steel Corrosion-Resistant Compression Springs 11 mm Long, 3 mm OD, 2.280 mm ID
  • The washer part number is 98689A243 - 18-8 Stainless Steel Washer for M1.8 Screw Size, General Purpose, 1.98 mm ID
  • I didn't use spring 2006N213 - 302 Stainless Steel Corrosion-Resistant Compression Springs 12 mm Long, 3 mm OD, 2 mm ID
