Leader CV Spouts ???

[spud]

We've used CV's almost exclusively since 2010 and of the 20,000+ we've installed in that timeframe we have not had a single one break. Hitting the CV too many times with the nylon hammer can cause the ball to pop out but that's been the extent of our issues.

That's impressive to not have even one CV2 spout break out of 20,000. I have put in 18,000 in the last three years and have broke some. In the three years I have probably broke 100 and I don't think thats bad at all. When I buy spouts I always buy 2-300 more then I need just in case. I have always used a framing hammer to put spouts in and do not plan to change. Theres no way you're pulling my spouts out with two hands. It's going to take two horses. If you're not cracking the tree then giving them a few more hits will not hurt anything. I maintain very high vacuum and do well with my overall GPT every season.

Spud - we use CV's and stubbies not CV2's. We are not yet on high vacuum (that will be in place for next year) so my tune on how hard we drive them will likely change in 12 months time! We use a slotted, curved piece of bar steel to pull the taps and it seems to be gentler on the spout and the tree than a claw hammer.

Using CV 1's with stubby and have had no problems with breaking or cracking / Have 9000 in this year . We try to achieve 27 inches of vac and when the tubing is tight there is no issue with using the two piece spout and adapter for getting high vac
My other business is running a paint shop and we paint all kinds of plastic parts and I can tell you there is never perfect parts all the time
extruding plastic has many variables i.e. type of raw materials temperature of extruder weather that day if mold is a little dirty or porosity shows up different places on different batches etc. So different spout manufactures are going to have issues from time to time I think all and all most of our spouts are made correctly and that's when we are happy with the brand we use
I have never had any problem with cv's backing out of the hole in cold weather as some types of plastic is prone to. I also do not want to walk my lines twice first putting on the spout then back through to tap I so all at once

I have both in my woods right now. Have been using cv1 spouts for the past three years. They both have their pluses, but, neither are perfect.

Those were the only 3 out of 2000 that we found were cracked. We've been using them since 2010 also and have never had any problems with them other than a bag a few years ago that was brittle, and the stubby cup was splitting.
