Frequently asked questions
How do I check cartridge cavity compatibility?▾
Sun cartridges install into standard cavities defined per series, so as long as the cavity standard (thread size) of your existing manifold matches, functional replacement or upgrade is possible. We can confirm the cavity standard from the model code.
Do you also support complete manifold assemblies?▾
Yes. Beyond individual cartridges, we can work with you on manifold assemblies configured to your circuit requirements.
