A five-cent O-ring is often the only thing standing between you and a catastrophic material crossover in your manifold.- Critical spray foam gun parts for manifolds
- Prevents fluid bypass in spray foam equipment
- Fits Fusion AP check valve assemblies
The Check Face O-Ring - 50/Pack from SPF Depot is your best defense against hidden internal leaks. We know that aggressive gun cleaners and hot ISO turn standard O-rings into mush, which is why we use high-grade elastomers designed to resist swelling and chemical attack. If you are rebuilding your fluid manifold and notice the check valve face isn't sitting flush, or if you spot material weeping between the gun head and manifold, this O-ring is the likely culprit. Never try to reuse these; once compressed, they lose their sealing ability. Unlike generic spray foam gun replacement parts, ours maintain their shape under heat, ensuring a tight seal every time you mount the spray foam gun. Order now.
- Replace it every time you pull the manifold
- Resists swelling from harsh solvents
- Bulk pack ensures you are always ready
