This Teflon O-ring is the small white seal inside LUCCA Flow Control devices. It creates the tight seal necessary for smooth, consistent pressure regulation during pre-infusion and extraction. Over time, wear or calcium deposits can compromise the seal—replacing this O-ring restores your flow control to factory precision.

Key Features

• Genuine Teflon construction for durability and chemical resistance
• Compatible with LUCCA Flow Control devices (E61 group head models)
• Maintains precise hydraulic pressure regulation
• Quick replacement—no special tools required
• Affordable preventive maintenance for consistent shot quality
