Hello,
I'm wondering if anyone can explain the disparity between the range of gland sizes to backup ring sizes in AS4716 vs AS5781? For example, AS5781 -1XX sizes go from -104 to -139, but AS4716 gland sizes go from -104 to -149. Is there a reason that -140 through -149 are excluded from AS5781? Likewise for gland sizes -231 through -247. AS5781 states the BURs are designed specifically to AS4716, and I can't find any language anywhere to explain the absence of the larger diameters.
Thanks,
Speck
