Design and features of clamp saddles
The clamp saddle is a highly cost-effective fitting designed to establish threaded branch outlets on polyethylene lines. It consists of two molded polypropylene halves encircling the pipe, secured tightly by high-tensile metallic bolts and nuts. A molded elastomeric seal ring seated in an engineered groove around the outlet compresses against the pipe surface, ensuring an immediate hydrostatic seal.
Conforming with ISO 17885 principles, the saddle contour distributes bolt clamping pressure evenly around the circumference to prevent pipe ovality or localized pinching. The top threaded female boss accepts sprinklers, pressure gauges, air release valves, or threaded secondary lines.
Sizing combinations and field drilling tips
Clamp saddles are typically produced to fit pipe outside diameters from 32 to 315 mm with female threaded outlets of 1/2", 3/4", and 1" (nominal_size_in), ideal for agricultural irrigation and utility takeoffs.
During installation, clean the pipe surface, seat the gasket correctly, and tighten the bolts in a cross pattern to ensure balanced torque. Once secured, drill through the threaded boss using a hole saw to penetrate the pipe wall. Detail your pipe diameter and branch thread size in our inquiry form for formal submittals.

Clamp Saddle — FAQ
What sizes are typical for clamp saddles?
These saddles typically accommodate pipe diameters from 32 to 315 mm with threaded outlets of 1/2", 3/4", and 1".
Are adhesives or heat needed when installing clamp saddles?
No, sealing is entirely mechanical via the compressed elastomeric gasket; no adhesives, solvents, or heating tools are required.
What material is used for the saddle clamping bolts?
Bolts and nuts are typically forged from high-tensile steel with anti-corrosion zinc galvanizing to resist moist soil conditions.
When should the hole in the pipe wall be drilled?
The saddle should be fully positioned and bolted to the pipe first, followed by drilling through the threaded boss into the pipe wall.
