Simple, low maintenance clamping mechanism. Rugged drag coupling is designed for use on rough terrain. Field-proven results for over 15 years in the agricultural industry. Internal connecting tube prevents gasket from pulling away. Gasket design takes advantage of fluid pressure to help create aid in the seal. Relatively inexpensive to replace if damaged. Great connection strength than standard Victaulic fittings. Truly re-attachable fitting allows for easy fix in the field. No reducing adapters needed. CNC machined from 6061-T6, lightweight aluminum. Anodized to Type II and Type III standards. Stainless steel bolts and zinc plated connection clamp provide a well-rounded heavy duty coupling.
