Zero Leak technology
Zero Leak Technology for Hydraulic, CNG, and Fuel System Sealing
Leak-Proof Plugs and Fittings for SAE/ISO Straight Thread O-Ring Boss Ports
Zero Leak Plug and Fitting technology incorporates a corresponding tapered seal surface on the male boss that mates with the tapered surface at the mouth of SAE and ISO Straight Thread O-ring Boss Ports. These locking tapers create a high-integrity metal-to-metal seal, additionally supported by an O-ring seal, delivering no-weep and no-leak performance in virtually any operating environment.

Locking Tapers for Straight Thread O-Ring Boss Ports (SAE / ISO)
Zero Leak Plug and Fitting technology incorporates a corresponding tapered seal surface on the male boss that mates with the tapered surface at the mouth of SAE and ISO Straight Thread O-ring Boss Ports. These locking tapers create a high-integrity metal-to-metal seal, additionally supported by an O-ring seal, delivering no-weep and no-leak performance in virtually any operating environment.
Flare-o™ Design
The Flare-o™ design mates with the standard 37° flare system, but adds multiple independent metal-to-metal seals plus an O-ring seal. The O-ring size is carefully specified to be smaller in cross-section than the space available, creating a dynamic seal rather than a static gasket—helping the connection stand up to vibration, temperature variation, and pressure spike conditions.
The Zero Leak Technology stands up to the rigors within your system and will not leak! Period!
Why Zero Leak Outperforms Traditional Threads
Zero Leak™ Port Entry Plugs and Fittings offer significant advantages over traditional NPT threads and other straight thread O-ring seal systems. They are engineered to not leak or back out due to:
-
Vibration
-
Temperature change and thermal cycling
-
Pressure spike variations within the operating environment
No Chemical Sealants Required
Zero Leak Port Entry Plugs require no chemical sealants, reducing the risk of fluid system contamination and simplifying installation.
