Good question, perhaps to allow for field conditions having the MIN. & MAX. variance might provide a degree of installation flexibility? But a response here, would be nice.
If the spigot had a definitive stop built into the bell, that connection by design becomes a lot less flexible. It no longer allows for deflection in the joint which can be utilized during construction to keep your pipe aligned or on target. Within allowances of course. Also shifting soils or poor compaction can stress that joint. Having the gasketed and flexible joint allows this to still function. This is a more versatile and superior design. It does require some skill by the contractor/installer though. Hope that helps.
In your video, I noticed two installtion requirements, not covered, that my engineers I contracted with were adamant about. 1) All installed pipe must have the pipe lettering installed on the top of the pipe. The purpose is for a near perfect straight line for installing employees to "observe a straight line installation." 2) Additionally, the lettering placed up on top is for future workers that may dig down to repair pipe failures in the future. The workers can clean the failed pipe's surface to see the pipe diameter, pressures' rating, class of pipe, giving them an observed specification before making the total excavation, allowing them to be sure they have the same "like specificed product" on hand to make the repair. This is rarely needed but on multiple occasions I had to be sure of what I needed. I noted on 3-4 occasions I had non compliant/specified materials on hand for the repair causing the correct products to be ordered/bought to make the acceptable repairs. 3) The spigot ends from the bevel end to the 'black line' should never be allowed to touch the ground, dragged through small stones (i e...sand, pea gravel, road side aggregate base rock, riprap, NO FOREIGN MATERIAL OF ANY KIND, etc.) before the installing employees have full control of the spigot end which is to prevent scratches, cuts, gouges or incidential minor injury to the spigot's end. Contractors' employees are notorious for allowing this to happen and when doing high pressure testing after all installions are completed "a leak can, will and has happened" allowing the pressurized testing to fail. Those infinitesimal scratches (maybe .001"-.005"+ deep) in the spigot's end are hard to determine which pipe joint is the failure. I'm speaking from 47 years of experience of being the General Contractor, having to be observant and firm with the employees doing the actual installation. As a side note I think the manufacture should wrap protection on the spigot's end, leaving the installion employee the one to remove the protection just before inserting into the bell. This is a similiar situation like "don't get contaminates in your lube." Just my 2 cent opinion!
Why wouldn't they make it to where it would stop where it should be?? What's the reasoning??

@@kyleschumacher7184 thanks Kyle. Well stated!
Thanks❤❤❤❤
You wouldn’t believe the ways I’ve seen some of these cowboys home pipe 😂
