sanitary couplings

Tri Clamp Sanitary Couplings

Stainless steel sanitary couplings for screw pipe connections and for expanding and welding are made for use of the transfer of food, beverage, chemical or pharmaceutical particles in food and chemical industry.

Male couplings with (RD) thread and female coupling with cone head (liner) are compressed with food-grade sealing material in between and closed by a round screw-on nut.
