I am interested in finding specifications, or a link, to a replacement for OMC dual line pressure tank connector springs. As best as I can measure, they are approximately 1 5/16″ long by 1/4” diameter. Any help is appreciated. Thanks.

Thanks Richard and labrador-guy. Just looking for an inexpensive replacement for these springs. Both Ace Hardware and Grainger are nearby.

Check some ball point pen springs. Lots of sizes that may work.

This is a very old thread, but in case folks are googling this, a perfect replacement from McMaster Carr is part 1986K66. https://www.mcmaster.com/1986K66/

Description:

302 Stainless Steel Corrosion-Resistant Compression Springs
1.375″ Long, 0.25″ OD, 0.21″ ID

Old on right, new on left.

Sometimes the best answer takes about six years or so to arrive. These springs do look to be a very good replacement. Thanks for posting this helpful information.
