American Seal and Packing delivers a full range of rotary mechanical seals configurations and component materials – to handle virtually any fluid moved by any equipment. When you Specify an ASP mechanical seal you are specifying quality. We offer our own and well-established brands. Our seals are produced by both USA and European brands providing both USA (Imperial) and Metric sizes.
American Seal & Packing
American Seal & Packing offers common pump seals, including in-line seals, Single Spring, Multi-Spring and Metal Bellows as well as basic single cartridge seals.
We have recently partnered with ASI (Advanced Sealing International) to provide highly engineered seals for problem industrial applications. This new addition allows us to solve problem mechanical seal applications
We also offer replica seals of German manufactured mechanical seals including Burgmann. Designs include standard Cartridge, split seals, pump & compressor seals, gas lubricated seals, agitator & mixer seals, and supply system and components.
If you need a seal to match your OEM seal we can help. Mission, Goulds, Fristam, APV, Alfa Laval, Grundfos, etc. We supply them.
Latty Split Seal

ASP-SPX Split Seal
Rotating Face Mechanical Seals:
Mechanical Shaft Seals Are The Best Way To Seal A Pump. Face Seals Prevent Leakage Better Than Packing And If Selected Properly Will Last Longer. Mechanical Seals Used In Clean Well Lubricated Applications Can Last 20 Years. Seals Can Be Constructed In Single (Allowing Only A Vapor To Escape) Or Double Configurations to meet fugitive emission requirements.
Shaft Seals Are Engineered For Shaft-Sealing Applications To Serve Original Equipment Manufacturers Or Field Replacement Requirements, Our Seals Will Hold Up To Difficult Applications. We Can Also Asset In The Conversion From Braided Pump Packing To A Mechanical Seal.
American Seal & Packing Delivers A Full Range Of Rotary Mechanical Seals Configurations And Component Materials – To Handle Pump Service Requirements In A Wide Range Of Industries. . When You Specify AS&P Seals You Have The Advantage Of Proven Reliability. When We Need Engineered Seals For Difficult Applications We Utilize The Engineering Departments Of Some Of The Top Mechanical Seal Manufacturers In The World including ASI, Latty, and Flow Serve.
We Also Supply Replacement Rotating Face Units And Seats For Industry Standard Seals As Well As Doing Complete Repairs.
Mechanical Seals Feature:
- *Invisible leakage
- *Less friction/power loss
- *No to little wear on the shafts or sleeves
- *Flexibility – to accommodate shaft deflections and “End Play”
- *No period maintenance
- *Long Life
As mechanical seals have evolved
They have become more reliable, more capable of handling ever wider application ranges, and more complicated. Understanding the basics of “how a mechanical seal functions” will help you understand the value of using the best available technology.
Fundamentally, every seal will have a stationary part and a rotating part. While companies like John Crane (who we are not affiliated with) and Durametallic (now Flow Serve) have argued which seal face should be harder. Most seal companies will agree it does not matter and the argument was over the marketing of a “better mousetrap”. The seal faces will run against each other and both are lapped and polished to 2-3 light bands (roughly 6 millionths of an inch). The flatness of the seal faces prevents any leakage other than a vapor. Double seals prevent the vapor from getting out in AQMD/EPA fugitive emission sensitive applications.
3 key areas need to be sealed for a mechanical seal to perform properly. Along the pump shaft, a rubber bellows, o-rings, or PTFE / Flexible Graphite wedges are used to prevent leakage along the shaft. At the entrance to the pump’s stuffing box, an o-ring or gasket is used to prevent leakage from escaping from it. And 3rd the area between the seal faces.
The 1923 first invention of the mechanical seal that would seal a rotating shaft with no visable leakage has come a long way.
There is no sealing device more expensive than a cheap one.
We are unique. Most distributors are tied to one major line and promote only that line. We offer multiple lines because no one sealing company is good at, or most cost effective in all the product segments they offer. Let us help you get the most for your money.
The most common question we get is what should i use, Pump Packing or a Mechanical Seal?
Packing is excellent in a wide range of applications. The factors to consider are is leakage acceptable, and what cost target are you trying to stay under in the short term and long term. Mechanical seals are generally more expensive initially. However the longer you keep your pump in service, the more cost effective a mechanical seal can be. Most packings must leak an average of 6 drops per minute (with the exception of flexible graphite), to lubricate the shaft. American Seal & Packing stocks both packing and mechanical seals, and can help you decide what is best in your application.
