In the past, Aviation Fuel sample connections requiring a shut-off valve were constructed from off the shelf parts configured into a kit. These kits included a separate probe, valve and Quick Disconnect, resulting in multiple connections and O-rings. The Coupling was assembled by pipe fittings with Teflon tape sealant. These kits were assembled by the customer, often requiring an extra labor cost seldom accounted for.

ASTM Aviation Fuel Particulate Contamination test method D 2276, A2.3 requires a sample point. Part 2.3.1 states …“Care should be taken in such cases to avoid trapping or general contamination”…and 2.3.2. “Sample Valve Connection…must have a minimum of internal recesses which could cause the hold up of contamination”….

With this in mind, we developed the ACCU-SAMPLE™ (Patent Pending) Quick disconnect with integral ball valve and probe. The ACCU-SAMPLE™ surpasses currently existing designs by eliminating multiple connections and recesses where contaminate, particulate and/or sediment might be trapped. This ensures accurate sampling. The unibody design utilizes only one ¼ “ npt connection, resulting in three times less leak points than other designs. To further minimize internal recesses, internal threads exposed to fluid discharge path have been eliminated. Special handle design will not allow coupler to be engaged or disengaged while ball valve is in the “OPEN” position. Coupler ends are interchangeable with existing manufacturers actuators. Through advanced design the ACCUSAMPLE ™ offers a better solution for your sampling connection needs.
