![[YUKEN] β F5 Pipe Flange Kit (SAE 4-Bolt, Standard Pressure Series)](https://img.prosourcemro.com/2026/05/002-174-300x167.png)
F5 Pipe Flange Kit (4 Bolt Solid Flanges, SAE). The mounting-face dimensions conform to the SAE 4-bolt flange Standard Pressure Series. Three mounting types: A = Rc thread, B = socket weld, C = butt weld. The port flange includes bolts and an O-ring. For the butt-weld (C) type, use JIS G 3455 high-pressure carbon-steel pipe, schedule 160. Hex socket bolts per JIS B 1176; bolt tightening-torque tolerance +/-10% applies when used on pressure lines.

Air Bleed Valves. Attached to the pump discharge side, the valve automatically discharges air that has entered the circuit. Connection bore Rc 3/8, maximum use pressure 25 MPa, blow-off pressure 0.15 MPa, cracking pressure 0.34 MPa. Three blow-off flow ratings (2 / 5 / 10 L/min) are selected according to the pump discharge rate.

![[YUKEN] β YC-100 Contami-Kit (Hydraulic Oil Contamination Measuring Device)](https://img.prosourcemro.com/2026/05/002-175-300x245.png)
Contami-Kit (Microscopic Inspection Device) YC-100. A portable measuring device that determines the contamination level of hydraulic fluid by comparison with standard contamination plates; the level can be obtained as a NAS1638 class (reference value). Reliable and simple to handle. Usable anywhere (portable, AC/DC switchable power). No skill is required since it compares against contamination plates. Measurement takes about 10 minutes. Records can be kept by photograph using a standard SLR camera. Options: water/glycol-fluid filter set (M-KYC-100-F-20) and 4x objective lens (KYC-100-L-20, 40x total magnification, for samples with relatively large, widely distributed contaminant particles). Separately sold parts include camera adapter, vacuum pump kit, filter/glass bottles, funnel, clamp, stand, spare bulb, filter set and cleaning solution. Note: the cleaning solution (KYC-100-N-20) is a flammable substance and cannot be handled for transport by air or ship - purchase solvent locally.
