Someone help me explain hose size and fittings.
Can someone explain to me what all these things mean like 10AN hose, -6AN, 1/8" NPT, 8 AN O-ring. I am going to buy the GE sandwhich plate adapter, but no idea what fitting sizes I need. I tried to look this up but can't seem to find the explanation. Ty
Re: Someone help me explain hose size and fittings.
AN is the outer diameter of the tube or hose divided by 16 in inches. These are commonly referred to as socketed or tapered fittings (as opposed to barbed AN hose ends) that seal on the 37 deg tapered face and no sealant is required by design. Example: -4AN is 4/16" = 1/4", -16 AN is 16/16" = 1" OD
NPT is a tapered thread using standard units of measure (I.e. Inches). This is different from the metric version categorized as BSPT. Some sizes are similar enough to be equivalent if the tolerances are loose enough - such is the case between 1/8" NPT using 27 threads per inch vs 1/8" BSPT using 28 threads per inch. Tapered fittings seal against the tapered threads using Teflon paste, Teflon tape, or anaerobic silicone sealant as a lubricant. Rven tho they are intended to seal on the threads, the lubricant also helps to prevent weeping.
AN o-ring uses the same OD tube diameter system for sizing but the joint using a machined embossmrnt to provide a seat for an o-ring to create the seal. It's commonly referred to as the acronym ORB (O-Ring Boss).
It's not comprehensive but maybe it'll get you started.
