Why Everyone Searches for Garlock Sealing Technologies Photos (And What They Actually Need)
You probably clicked on this because you found a stamped part number on a seal somewhere and need to verify it, or you are trying to document what is installed in a press for a maintenance report. I have been doing this work long enough to know that the visual reference materials from Garlock are scattered across their site, some PDFs are decades old, and the images you find on third-party distributor sites are often wrong resolutions or mislabeled. The company itself does not publish a clean catalog gallery you can just browse. Garlock makes elastomeric seals, PTFE seals, hydraulic rod seals, pipe seals, and custom-machined components. When people search for photos, they are usually trying to distinguish between a standard NBR O-ring and a PTFE energized seal, or they need to confirm the cross-section profile of something like a Garlock Lipseal or a V-ring pack. The problem is that most of their official imagery is embedded in technical bulletins rather than standalone product photos. You will typically find images in their SEALS & SYSTEMS catalog PDFs, on their product pages at garlock.com, and in legacy datasheets that still circulate through engineering forums. I spent about three weeks last year tracking down correct images for a retrofit on a hydraulic press that had been sitting for twelve years. The original seals were a mix of Garlock and someone else's brand, and the equipment manual was from 2004. The drawings in the manual did not match the actual installed hardware. I ended up pulling Garlock Sealing Technologies Photos from their technical literature archive, cross-referencing them with part number plate readings, and then confirming dimensions by taking the seal off and measuring it with digital calipers before committing to an order. This took about four hours total but saved me from ordering the wrong replacement and having to tear the machine apart again.
How to Find the Right Images and What to Watch Out For
The most reliable source is still the official Garlock website, specifically their technical resources section. Search by part number if you have it. If you only have a drawing number or an equipment manufacturer part number, you will need to work backward. Garlock's part numbering system encodes material, profile, and size in the alphanumeric string. A typical seal part number like GK-LPS-350X380X10 tells you the series, the inside diameter, the outside diameter, and the cross-section. The image you find should match those dimensions exactly. Here is something most people miss: Garlock has changed material specifications over the years. A seal that looks identical in a photo from 2008 may have a different base compound than the same part number produced today. They use different nitrile grades, different PTFE formulations, and different fillers depending on the production batch and the customer specification. If you are sourcing replacements for an existing installation and the equipment runs at elevated temperatures or in aggressive media, do not assume the photo matches the current material datasheet. Check the latest spec sheet for the exact part number before ordering. I ran into this exact issue on a wind turbine pitch system retrofit. The original Garlock hydraulic rod seals had degraded and I ordered replacements based on the part number visible on the old seals. The photos looked identical. The new seals failed within six months because the original specification called for a perfluoroelastomer (FFKM) compound and the current standard production run used a different fluoroelastomer (FKM) grade. The external dimensions were the same, the photo was the same, but the chemical resistance was not. I had to pull a sample and send it to a lab for FTIR analysis to confirm the material mismatch. It cost about $400 in testing and a week of downtime, but it saved me from replacing the entire seal fleet on that turbine with the wrong compound.
When you are pulling images for documentation purposes, I recommend downloading the actual PDF datasheets rather than trying to screenshot product pages. The resolution is better, the captions include the material grade and temperature range, and you can reference them later without hunting for the URL again. Garlock's PDFs also include fitment diagrams and installation notes that their web images strip out.

Common Pitfalls When Using Reference Photos for Seal Selection
The biggest mistake I see is people matching seals by looking at the photo alone. Two seals can look exactly the same in a product image but have completely different cross-sectional shapes. A square section seal and a rectangular section seal will both appear as dark rectangles in a low-resolution photo. Always measure the cross-section. A 5mm square seal is not interchangeable with a 5mm round seal, even if the bore diameter matches. Another issue is the difference between static and dynamic applications. Garlock makes seals that look nearly identical for static gasket use and for dynamic rod seal use. The installation groove is different. The surface finish requirement is different. A photo will not tell you which one you need. The part number and the application context will. If you are putting a seal on a moving rod, you need a dynamic seal design with the right friction characteristics and wiper edge. A static seal in that position will leak within days. There is also the problem of obsolete part numbers. Garlock retires part numbers regularly and replaces them with updated versions. The old photo might still be indexed on Google Images with the superseded part number. If you find a photo for a part number that is no longer listed on the current Garlock site, it is likely obsolete. Cross-reference with the equivalent new part number on their site before making any purchasing decisions. The fit might be the same or it might have subtle changes to the lip geometry or backup ring design.
What I Use When the Official Photos Are Not Enough
When I need visual confirmation beyond what Garlock publishes, I pull from a few places. Distributor sites like Motion Industries, Applied, and Parker Hannifin sometimes have higher-resolution images than the manufacturer site. Third-party seal identification guides, particularly the ones published by seal engineers on industry forums, are useful for cross-referencing. I also keep a physical reference library of common Garlock seal profiles that I have measured and photographed myself over the years. This is more reliable than any online image because I know the exact dimensions and the material each one is made from. If you are doing this work professionally, I would recommend building your own reference archive. Take a macro photo of every seal you pull from equipment, label it with the part number, material, application, and date. Your future self will thank you when you need to identify that mysterious seal in a machine that has no documentation. I have a drawer of labeled Ziploc bags with about 200 seals in it, each with a handwritten tag. It sounds primitive but it has saved me more than once when I was on a job site with no internet access and needed to identify a seal under time pressure. The reality is that Garlock Sealing Technologies Photos are useful for identification and documentation but they are not a substitute for verifying part numbers, material specs, and dimensional tolerances against the actual equipment. The images are marketing and reference tools, not engineering documents. Treat them that way and you will save yourself a lot of trouble down the line.
