Bomag 05546116 Screw Plug with Seal

The Bomag 05546116 Screw Plug with Seal is a genuine OEM component designed for a wide range of Bomag cold milling machines, pavers, tandem rollers, walk-behind rollers, pneumatic tyred rollers, and recyclers/stabilizers. Sourced directly from Bomag, this plug delivers an exact fit and proper sealing performance across every compatible application. Compatible equipment includes BF-series pavers such as the BF 300 P, BF 600 P-3 S 500, BF 700 C-3 S 500, BF 800 C-3 S 600, and BF 900 C S600, BM-series cold milling machines including the BM 500/15 Stage V, BM 1000/35, BM 1200/35, BM 1300/35, BM 2000/75, BM 2200/75, and BM 2500/75, tandem rollers such as the BW 120 AD, BW 154 AP-4, and BW 174 AP-4, walk-behind rollers including the BW 62 H, BW 65 H, BW 75 H, and BW 75 E, pneumatic tyred rollers including the BW 11 RH-5 and BW 28 RH, and recyclers/stabilizers including the RS 460 and RS 500. Choosing an authentic Bomag part ensures the sealing interface is maintained to the original specification, protecting fluid containment and system integrity across every application.

Key Features

• Genuine OEM Sealing Integrity — manufactured by Bomag to the original material and thread specification, ensuring the plug and integrated seal form a leak-free closure under operating pressures.
• Drop-In Thread Compatibility — this screw plug threads directly into the original port without rework, maintaining the original torque and seating geometry.
• Broad Fitment Across Bomag Equipment Lines — fits BF-series pavers, BM-series cold milling machines, BW-series tandem and walk-behind rollers, pneumatic tyred rollers, and RS-series recyclers/stabilizers, including models such as the BF 600 P-3 S 500, BM 1000/35, BW 174 AP-4, and RS 500.
• Fluid Containment Assurance — a correctly functioning screw plug with seal prevents hydraulic fluid, oil, or coolant loss at ported surfaces; a degraded or missing plug risks contamination ingress and fluid leakage that can escalate into major system damage.

A screw plug with seal closes off a threaded port on a hydraulic, lubrication, or coolant circuit, acting as a permanent or service-access cap that prevents fluid from escaping and contaminants from entering. The integrated seal — typically an O-ring or bonded sealing washer — compresses against the seating surface as the plug is torqued down, forming a pressure-tight closure that the plug alone cannot achieve. When the seal degrades or the plug is missing, even a small port opening can cause fluid loss, air ingress into a hydraulic circuit, or contamination that damages pumps, motors, and other precision components downstream.
