Push Button Sample Ports Elastomeric Valve For use on engines, compressor, transmission & hydraulics (pressurized systems) Integrated probe (no external probes necessary) Sample while the equipment is running (>0 to 750psi) Reduce the time needed to take samples Less than 1ml (0.04 fl oz) of deadzone volume to purge Port $15 - $20 Ref: JK, CheckFluid
Push Pin Sample Ports Elastomeric Valve For use on engines, compressor, transmission & hydraulics (pressurized systems >0 to 750psi) Typically used on off-highway, mobile and marine equipment Less than 1ml (0.04 fl oz) of deadzone volume to purge Variety of probe options for hand sampling and higher pressure dynamic sampling. Port $15 - $20 Adapter $10 - $15 Ref: JK, CheckFluid
Minimess Static Sampling Tubes
Uses standard minimess style sample port Meant for zero pressure applications Available in Stainless Steel Assembly $40 - $55 (steel)
Ref: JK, CheckFluid (Images)
Minimess Valve Mount Sample Ports Uses standard minimess style sample port Add oil sampling valves while pipe and tubing is pressurized, without shutting down and interrupting plant operation. Install and operate under pressure up to 6000psi Install only on tube, not to be used on schedule 80 & 160 pipe Installation in only a few minutes with no special tools required. No cutting open pipes or special adapters required. Port $150 - $200 Ref: JK, CheckFluid
