Where Can I purchace the pneumatic conectors that allow the pneumatic hose to press in and grab. Thank you.
Those compression fittings are sold by SMC http://www.smcusa.com/default.asp that are included in the KOP. There are other suppliers out there too but SMC is the most common.
Can we replace the push-on valves with compression fittings?
Also Allied Electronics is a good mail order source for SMC pneumatics and fittings, but not 12VDC valves. www.alliedelec.com . They ship same day. http://www.alliedelec.com/catalog/pf.aspx?fn=1478.pdf&pageNum=1478
As far as compression fittings, I personally wouldn’t bother. The SMC push-on fittings are great.
Grainger also has them, there may be a branch near you.
