Spectra High Pressure Tube Fitting Assembly Instructions
The Ventura Deluxe has eight high pressure fittings, two on each cylinder on the Clark Pump,
two on the pressure vessel end caps, and two 90-degree elbows on the back of the Clark
Pump. As the compression fitting is tightened, it compresses a ferrule onto the stainless tub-
ing, fixing the ferrule permanently to the tube and holding the compression nut captive.
The body of the fitting seals to the underlying component with an O-ring. On the Clark Pump
cylinders and the end caps this O-ring is compressed by tightening the entire fitting. The O-
rings on the 90-degree fittings on the back of the Clark Pump have captive nuts and washers,
which compress the O-rings without turning the entire fitting.
If a tube fitting leaks it can sometimes be resealed by just tightening. You must use two
wrenches, a 13/16-inch wrench to hold the base, and a 7/8-inch wrench to turn the compres-
sion nut. The 13/16-inch wrench will need to be thin so as not to interfere with the compres-
sion nut. If this doesn’t work, disassemble the fitting, grease liberally with silicone grease (the
ferrule and the threads) and re-tighten firmly.
The base O-rings should be gently compresses to achieve a good seal, and may be damaged by
overtightening.
