Dry Gas Seal Plans

Dry gas seals utilize a gas as the primary fluid to prevent leakage and lubricate the seal faces. This method is chosen because the process fluid to be sealed can have poor lubricity, be volatile, sensitive to heat, or have potential to polymerize fouling the seal face, or can be corrosive to parts of the seal. They are best for sealing off volatile fluids and exceedingly clean materials with virtually no process contamination.

Our dry gas seal plans can considerably improve your seal's performance as compared to a traditional seal flush plans in certain applications. They deliver the right amount of pressure and flow to remove seal-generated heat. Friction is the enemy, and an effective dry gas seal can significantly reduce costs associated with maintenance and unplanned downtime.

Swagelok products and assembly work are backed by our Limited Lifetime Warranty.

Plan 72 Buffer Gas solution

Our Plan 72 is extremely compact, potentially 3 times smaller than your current solution, leading to significantly less weight. 

Plan 74 Barrier Gas solution

Our API Plan 74 panel assembly contains 100% Swagelok components so the quality shines through, and you can have peace of mind that our materials and assembly work are supported by our warranty.

Plan 75 Condensing Leakage Collection solution

Plan 75 collects leakage from the inboard seal, and is typically used with a Plan 72 in applications with condensing leakage. It has a visual indicator on its reservoir that specifies when you need to drain it.

Plan 76 Noncondensing Leakage Collection solution

Plan 76 is used in conjunction with Plan 72 and vents leakage from the inboard seal to a vapor recovery system. 

Plan 72/76 Buffer Gas and Noncondensing Leakage Collection

You’ll be surprised when you see our solution because of its compact size and low weight. Mistake-proof labeling on this panel makes it easy to operate, increasing safety and making training simple.
