Do Not Weep
These silicone seals do not weep like composite washers will after prolonged periods.
Great upgrade.

Used to replace union seal on passive Caleffi HW Solar loop
Needed to add 1 inch valve to Caleffi HW solar heat exchange loop. Used these as replacement seals. Have been installed since 2021 with no issues.

Great replacement for paper washers
These washers seal a lot better than paper washers do.
