Home » Micron Inline Filter
SuperlokUSA® micron inline filters are precision-engineered for high-efficiency contaminant removal in fluid and gas systems where cleanliness, pressure integrity, and system protection are critical. These filters are designed to intercept particulates and impurities before they compromise your equipment boosting reliability, extending component life, and reducing unplanned maintenance.
Constructed from 316 stainless steel and other corrosion-resistant alloys, Superlok filters stand up to harsh media, high-pressure differentials, and demanding operating environments. The result: long-lasting durability and consistent performance across industries that can’t afford failure like chemical processing, semiconductor manufacturing, pharmaceuticals, hygienic fluid processors, and gas distribution systems.
Swagelok® is known for high-performance filtration components but Superlok micron inline filters offer a trusted alternative with the same precision, reliability, and clean installation… without the markup or long lead times. Built to meet or exceed industry standards, Superlok filters deliver the quality you expect, plus better availability and value.
Each filter is manufactured from 316 stainless steel and designed for precise fluid control in sensitive or high-pressure applications. These micron inline filters feature leak-tight construction, high-flow capacity, and corrosion-resistant bodies that match or outperform equivalent Swagelok® models. And with compact inline designs, they install cleanly into both new builds and retrofit projects without compromise.
If you’re looking for a filtration solution that delivers top-tier performance, fast turnaround, and full pressure system reliability Superlok’s micron inline filters are the clear alternative.

All Superlok Micron Inline Filters are designed with the same dimensions and flow characteristics as Swagelok® and Parker® filters, allowing full cross-brand compatibility in fluid and gas systems. That means the same filtration performance, comparable form, fit, and function without the long lead times or markup. The internal components and end connections of Superlok filters are manufactured in accordance with ASME B31.3 for process piping and ASME B16.34 for pressure-containing parts. Thread tolerances are controlled per ASME B1.20.1, ensuring consistent sealing performance and leak-free integration every time.
To validate performance, Superlok’s inline filters undergo third-party testing for burst pressure, pressure drop, and particulate retention, and meet strict standards for use in sensitive and high-pressure filtration environments. For reference, we’ve attached the full SGS interchangeability & burst-test certification for your review.

Previously, we used cheap connections that always came loose and leaked gases. Since we have switched to Superlok, we have had no issues of gas leaks. Their products are high quality with good prices. Wren has been very helpful with our orders, always sending updates on the status of our orders. I would definitely recommend Superlok.

Rodney LacyJune 23, 2023Trustindex verifies that the original source of the review is Google. While installing some import German equipment we needed to adapt from Metric to standard. We called Swedglok; the manufacture of the German end of the problem. It took 30 minutes to figure out what I was needing and to find that it will take a week to get it. I called Superlok. Wren knew right away what I was talking about. She had the solution in stock. During the exchange I needed to call her a number of times to up the quantity or change freight to early AM delivery. Wren was easy to reach and I felt her smile from my end of the phone. Good companies are made Great by the staff they employee. If this was an interview, I would hire Wren.
