Instructions : how to Preswaging

When installing Swagelok tube fittings in cramped quarters or where ladders must be used, it may be advantageous to use a pre-swaging tool. It allows the
preswaging of ferrules onto the tube in a more open or safe area. After using the tool simply follow the retightening instructions.

Oversized or very soft tubing may occasionally stick in the tool after pull-up. If this happens, remove the tube by gently rocking back and forth. DO NOT TURN the tube with pliers or other tools as this may damage sealing surfaces.

1. Assemble Swagelok nut and ferrules to preswaging tool. Insert tubing through ferrules until it bottoms in the preswaging tool, and tighten nut 1 1/4 turns.

2. Loosen the nut and remove the tubing with preswaged ferrules from the preswaging tool.

3. The connection can now be made

STEAM / CONDENSATE SYSTEMS VALVES

When the operating pressure is 80 psi and above, the system shall be considered high pressure. Where operating pressures is between 15 – 79 psi, the system shall be considered medium pressure. When the operating pressure is below 15 psi, the system shall be considered low pressure. In order to improve standardization and quality, steam/condensate system valves, operating in the medium and low pressure class, shall utilize the same type of valves per the following size/application schedule:

Size Range	Application	Operating Pressure	Valve Type
¼” – 2”	Steam/Condensate	80 psi & above	A1
¼” – 2”	Steam/Condensate	Below 80 psi	A2
2 ½” – 8”	Steam/Condensate	80 psi & above	B1
2 ½” – 8”	Steam/Condensate	Below 80 psi	B2
10” & up	Steam/Condensate	80 psi & above	C1
10” & up	Steam/Condensate	Below 80 psi	C2
¼” – 3”	Domestic Hot/Cold Water	125 psi & above	D1
¼” – 3”	Domestic Hot/Cold Water	Below 125 psi	D2
4” & up	Domestic Hot/Cold Water	125 psi & above	E1
4” & up	Domestic Hot/Cold Water	Below 125 psi	E2
¼” – 3”	Chilled Water	Below 125 psi	D2
4” – 10”	Chilled Water	Below 125 psi	E2
12” & up	Chilled Water	Below 125 psi	F1
¼” –  3”	Condenser Water	Below 125 psi	D2
4” & up	Condenser Water	Below 125 psi	F1
