Jet Ejector & Condenser Spare Parts

Made in the USA

JET-VAC® Technologies provides in-house manufacturing, for all ejector components, with the highest quality of standards. To ensure quick delivery, we promote exacting design, with inventory consisting of finished components, castings, and raw materials.

Our standard material offering for nozzles is 316 grade stainless steel – other materials are available upon request. For some components, we can even offer same day shipments, which will minimize your facility downtime.

Keep An Inventory of Spare Parts

An inventory of recommended spare parts (nozzles, diffusers, and gasket sets at a minimum) helps avoid down-town in your facility. It is recommended to have a reserve inventory, either proactively stored at JET-VAC® (ready-to- go) or made and shipped, with your equipment, at the time of initial purchase. This also protects against prolonged outage as most ejectors are custom-designed and it could take a few weeks to receive the replacement part.

Typical Ejector Spare Parts

The nozzle head holds the motive steam nozzle in place and conveys steam into the ejector.

Nozzles are one of the most critical components in the ejector. Over time it can deteriorate (orifice increases) resulting in poor performance. Spare nozzles are recommended to be kept in your inventory to minimize downtime.


Condenser Tube Bundles can develop leaks do to cracking and / or erosion. When this occurs, cooling water can pass through the process side, resulting in poor condenser performance. JET-VAC Technologies provides replacement bundles designed and manufactured to meet original performance requirements. We can also up-grade to other materials as required. When ordering bundles, be sure to request condenser gaskets as well.

Diffusers are critical components in the ejector. Over time, diffusers will deteriorate (scoring, cutting internal surfaces, product build-up, or throat diameter increases). The deterioration results in performance issues. To minimize downtime, spare diffusers are recommended to be kept in your inventory.


Suction Head conveys and mixes process vapors with motive fluids.

The inspection Plug allows for evaluating the nozzle orifices for signs of wear or plugging.

The gasket(s) are used to provide a leak tight system and should be replaced during routine maintenance. A gasket set is recommended to be kept in your stock.

The Strainer protects the nozzle orifice from clogging and should be cleaned when necessary and replaced when damaged.
