PIC Gauges NV-SS-1/2-HS-180-FXF 316 Stainless Steel Straight Needle Valve with Hydraulic Service Seat

im looking for a valve just like this one except it needs to be 1/8 NPT. do you sell one? thanks

I purchased a "nv-ss-3/8-hs-180-fxf needle valves a while back and the o-ring & back-up ring has broken, where can i purchase replacement o-rings?

What is the temperature rating of this valve?

What is the max gpm flow?
