Port Connectors
- Remove nut and ferrules from the first of the two Swagelok ports to be connected.
- Slip nut only (no ferrules) over the machined ferrule end of port connector.
- Insert port connector into Swagelok Port 1 and finger tighten the nut.
- Tighten with wrench 1/4 turn only. (For 1/16, 1/8, and 3/16 in.; 2, 3, and 4 mm size tube fittings, tighten 1/8 turn from finger-tight.) Subsequent connections are made from the finger-tight position by slightly tightening the nut with a wrench.
- Insert other end of port connector into Swagelok Port 2 until bottomed, and tighten nut 1 1/4 turns from finger-tight using normal Swagelok nut and ferrules. For 1/16, 1/8, and 3/16 in.; 2, 3, and 4 mm tube fittings, tighten 3/4 turn from finger-tight.
Plug
Tighten plug with wrench 1/4 turn from finger-tight position. For 1/16, 1/8, and 3/16 in.; 2, 3, and 4 mm tube fittings, tighten 1/8 turn from finger-tight.
For over 1 in. and 25 mm, tighten plug with wrench 1/4 turn from finger-tight.
Make subsequent connections by slightly tightening with wrench after snugging the nut by hand.
Swagelok to AN Adaptor
Tighten the Swagelok nut by hand. Rotate the nut with a wrench until an increase in resistance is encountered. Then tighten slightly with the wrench.
For nylon fittings, see the Assembly Instructions card shipped with each fitting.
SAE/MS Straight Thread – Positionable Elbows and Tees
- Lubricate O-ring with a lubricant compatible with the system fluid, environment, and O-ring material. A (Standard O-ring material is fluorocarbon FKM. Other O-ring materials are also available, upon request.)
- Turn the fitting into the straight thread boss until the metal back-up washer contacts the face of the boss.
- Position the fitting by backing it out (not more than one turn counterclockwise) until the Swagelok tube fitting end is oriented in the proper direction.
- Hold the wrench pad with a backup wrench and tighten the locknut until the washer is against the face of the boss.
NOTE: SAE/MS positionable elbows and tees are compatible with J1926, MS16142, or JIC female straight thread O-ring bosses. O-rings are coated with a thin film of silicone based lubricant.
Swagelok Adaptors
When installing pipe elbows or tees, it is often difficult to align the fitting with the desired run. When pipe threads are tightly engaged, an angle fitting is often pointing in the wrong direction for the tubing run. Loosening the pipe connection means
leakage at the pipe thread. By using Swagelok tube adapters in conjunction with union elbows or tees, these difficulties can be totally avoided.
Adapters can save money while providing greater in-system versatility.
NOTE: Swagelok adapters, reducers, and port connectors are to be used ONLY in Swagelok tube fittings. Use in fittings made by other manufacturers may result in failure.
Step 1. To facilitate the installation of adapter fittings, it is advantageous to first connect the end opposite the tube adapter end. This will eliminate alignment problems which are often encountered with fittings such as male run or branch tees.
Step 2. Place the Swagelok tube fitting over the adapter fitting. Make sure that the adapter fitting rests firmly on the shoulder of the Swagelok fitting and that the nut is finger-tight.
Step 3. Before tightening the Swagelok nut, scribe the nut at the 6 o’clock position. Now, while holding the Swagelok fitting body steady with a backup wrench, tighten the nut 1 1/4 turns. A Watch the scribe mark, make one complete revolution, and continue to the 9 o’clock position. For 1/16, 1/8, and 3/16 in.; 2, 3, and 4 mm size tube fittings, tighten 3/4 turn from finger-tight.
