What It Means
Union O-Ring Leak
Likely Causes
- Union O-rings dried out and cracking
- O-rings were lubricated with petroleum-based product (swells rubber)
- Unions over-tightened causing O-ring deformation
Next Checks
- Remove unions and replace O-rings
- Lubricate new O-rings with Teflon-compatible silicone grease only — never petroleum-based products
- Hand-tighten unions plus 1/4 turn — do not over-tighten
