Bijur Delimon – Meter Unit FB-4: Extra Fast Flow, British Thread Tee Type
L. Dewitt's SKU #: B8729 | Mfr Part #: B8729The Bijur Delimon B8729 Meter Unit (Type FB-4) is a precision oil proportioning device for Single Line Resistance (SLR) cyclic lubrication systems. The FB type features a 1/8 NPT inlet and a 1/8 BSPT outlet, making it the go-to tee-type unit for systems that mix American NPT supply lines with British Standard Pipe bearing connections. It delivers "Extra Fast" metered oil to the bearing point.
Regulated Extra Fast Flow
As a FB-4 model, this unit delivers Extra Fast flow, providing a high-volume oil delivery for the largest or most critically loaded bearing points in the system. Typically specified for oversized journals, large-diameter slides, and applications with extreme load or speed requirements.
Cyclic System Integrity
An integrated 5 lb check valve ensures one-directional oil flow (direction indicated by arrow on body) and prevents lines from draining during the pump's off cycle. For cyclic lubrication systems only. Not compatible with continuous-flow pumps.
