Air-O-Unions & Seal-O-Grip Unions
PME Air-O-Unions (also known as Seal-O-Grip unions or inflatable connectors) are the industry standard for fast, leak-proof connections in drilling mud systems. Engineered with a durable carbon steel body and an oil-resistant NBR inflatable tube, these unions allow for flexible alignment on mud tanks and manifolds.

| Body Material | Heavy-duty Carbon Steel |
| Working Pressure | Max 150 PSI |
| Seal Material | Oil & Abrasion Resistant NBR |
Key Operational Applications
Mud Tank Systems
Perfect for quickly linking active and reserve mud tanks, ensuring a secure seal between tank sections and transfer pipelines.
Suction & Return Lines
Reliable performance in suction lines between mud pumps and pits, accommodating minor pipe misalignment during rig-up.
Mud Cleaning Systems
Ideal for connecting shale shakers, degassers, and centrifuges within the primary mud circulation loop.
