Replacement RF Sealing Equipment Parts & Radio Frequency Welder Parts
Replacement RF sealing equipment parts and radio frequency welder parts need to be dependable, matched to your system, and ready when RF tubes fail or drift out of spec. At Penta Labs, we focus on high-performance power components for RF heat sealing and welding systems, helping OEMs and maintenance teams keep uptime high.
Our selection of radio frequency welder parts
We concentrate on the RF power section of your sealing and welding systems, supplying RF tubes and critical RF equipment parts that keep generators stable and output consistent.
From every matched triode vacuum tube to precision high-voltage vacuum capacitors, our inventory supports everything from compact sealers to high-duty production welders.
Whether you are maintaining legacy RF welders or building new platforms, our parts are selected and tested to deliver predictable performance under demanding industrial loads.
Our engineering and applications teams work directly with RF heat sealing OEMs to match tube and capacitor choices to real-world operating conditions, duty cycles, and form factors. This collaboration helps reduce field failures, simplifies service documentation, and gives your end users a clear, reliable path for replacement parts over the life of the machine.

Questions about our replacement RF sealing equipment parts?
If you are unsure which RF tubes are correct for your model, or you do not see your part number listed, our team can help you match the right RF sealing machine parts to your specific welder. Share your equipment brand, model, operating frequency, and application, and we will recommend appropriate RF welding and sealing components, confirm compatibility, and guide you toward reliable, long-term replacements for your production environment.
Trusted RF welding solutions for OEMs from Penta Labs
OEMs rely on Penta Labs for RF welding solutions that start with high-power electron tubes and extend through carefully matched RF power components. Our products are designed specifically for RF heat sealing and welding environments, with attention to real duty cycles, arcing risks, and thermal loads rather than generic specifications adapted from other markets.
We support RF welder and sealing equipment OEMs from design-in through field service, helping you select tube and capacitor families, standardise part numbers across platforms, and plan for lifecycle availability. Deep inventories, documented specifications, and consistent mechanical interfaces make it easier to write manuals, train service networks, and give your customers a clear, dependable source for replacement RF power components over the life of each machine.
