With over 40 years of installed history in the harshest of Australian conditions, Plasson fittings are the toughest, most reliable and easiest to install poly pipe fittings available.
The captive o-ring is not susceptible to falling out as with other fittings, and a seal is created when the pipe is pushed past the o-ring eliminating the need for excessive tightening.
Simply hand tighten the Plasson nut for a completely leak-free system.
