Press-Seal performs quality checks on boot connectors before they ever leave the building. But to ensure our customers always get the best possible product, we’re sharing key inspection techniques you can also complete yourself. View our boot connector inspection video to get started!
Press-Seal’s Mission
Press-Seal’s mission is to provide the highest-quality products possible each and every time—our company foundation is built around quality and service. Whether product inspection occurs after assembly or clear back at the beginning with our rubber mixing, our standards of quality remain unsurpassed in the market.
Inspecting a PSX: Direct Drive Boot Connector

Press-Seal PSX: Direct Drive stainless steel power sleeve.
The inspection of any boot begins with ensuring you receive the correct product and quantity before looking at the finer details—we want to make sure you get what you paid for!
As you dive deeper into the boot inspection, ensure your PSX: Direct Drive includes its power sleeve. This tempered series 304 stainless steel component is an extension of the sealing surface. Without it, a gap in the sealing surface could form and cause leaks in the field.
Next, locate the adjuster nut at the large end of the boot. It should rest within a molded horizontal groove. A nut installed backward causes the expansion band to install backward.

Inspecting a PSX: Nylo Drive Boot Connector
Similarities between the PSX: Direct Drive and PSX: Nylo Drive are almost transparent, but subtle inspection differences do occur.

PSX: Nylo Drive band.
Just like the Direct Drive, ensure the Nylo Drive’s reinforced nylon polymer power sleeve is present and undamaged. Without a properly functioning power sleeve, the seal might not form correctly, resulting in leaks. Its stainless steel adjuster nut should be visible within the expansion mechanism area, too.
Nylo Drive’s glass-filled nylo band features a black thermoplastic oversleeve that requires closer inspection compared to the Direct Drive
Inspecting a PSX: Wedge Drive Boot Connector
You’ve heard it once, you’ve heard it twice, and now, you’ll hear it for a third time: ensure all components of your PSX: Wedge Drive are present and undamaged.

Close-up on Press-Seal PSX: Wedge Drive mechanisms.
The Wedge Drive is a relatively simple boot with a construction employing no welds or rivets. Ensure its series 300 stainless steel power sleeve is present upon arrival to ensure uncompromised sealing action. Locate and confirm that all snap pins and take-up clamps are firmly affixed to the product, and you’re ready to begin installation!
Boot Connector Markings

PSX: Nylo Drive with markings.
An easy way to determine whether you’ve received the properly sized boot is to look for the molded text embedded right into the rubber. On both the PSX: Direct Drive and PSX: Nylo Drive, you’ll find:
- Our company name (Press-Seal Corporation)
- Pipe OD range
- Boot size
Other Inspections of the Boot
Our engineering team designed these boots with even the molds used to make them in mind. Press-Seal boots are manufactured per ASTM requirements and allow for a certain amount of flashing. Our specially designed molds ensure that any of the acceptable flashing is not found on the sealing surface itself. Should you have questions about possible flashing, please reach out to our team.
The final tip we use for boot inspection is quite straightforward: the boot must be round. We take preventative measures to ensure the packaging of our boots minimizes possible damage or ovality during transport to your project, but we cannot control shipping damage or the careless handling of the boot.
