Injection Quills

Optimized & Industry-ready Solutions

For All Your Complicated Needs

We build Injection Quills specifically for your injection needs and requirements.

ProMixUSA Chemical Injection Quills are used to introduce medium to highly corrosive chemicals into a pipeline without damage to the side port or pipe wall at the point of injection.  In addition, chemical injection quills ensure that chemicals are evenly dispersed into the center of the pipeline, which prevents channeling of the chemical down the pipe wall.  Also, the body and stinger are both constructed of chemical resistant plastics or alloys (PVC, Kynar, 316 SS, or Hastelloy C-276).  Finally, injection quills with 3” to 8” long stingers are available from stock.  Finally, all injection quills come with female by male MNPT threaded connections for ease of installation.

Material Options

PVC Injection with check valve


PVC rod (unplasticised polyvinyl chloride) is a rigid engineering plastic that provides high mechanical strength, excellent resistance to chemicals and offers low moisture absorption.

Hastelloy C-276 Injection Quill with Check valve

316L Stainless Steel

Stainless Round Bar 316 exhibits high strength and excellent corrosion resistance including in marine environments.  Also, 316 is slightly stronger than 304 stainless and is rated as a marine metal.  Furthermore, 316 maintains its properties in cryogenic or high temperatures.  Finally, it is typically used in oil and petroleum equipment, aerospace, food processing, pulp and paper processing equipment, textiles, architectural, and marine equipment.

Kynar Quill with Check valve

PVDF Kynar

Lightweight with high chemical corrosion resistance and high heat resistance, commonly used for chemical installations, pharmaceuticals and bioindustry applications, as well as for mining.  In addition, this partially fluorinated high-performance plastic is FM 4910 certified, non-toxic, FDA compliant, and features low flammability, excellent chemical resistance, exceptionally good aging resistance, and high rigidity.  Finally, PVDF Kynar Solid Rod is one of the most stable and chemically pure of all plastics.

Hastelloy® is a nickel-molybdenum alloy.  There are many different grades of Hastelloy®, many of which are nickel-chromium-molybdenum alloys.  Also, each of these grades has been optimized for a specific purpose, but all of them are highly resistant to corrosion.
