PA Rotary 3-Way Male BSPP Fitting

What Is a PA Rotary 3-Way Fitting?

A PA rotary 3-way fitting is a quick-connect pneumatic elbow. It has two push-in tube ports and one male threaded port. The body rotates 360 degrees after you install it. This lets you change tube direction without stressing the line.

We build PA rotary fittings with PA polyamide housings and brass thread inserts. The push-in design means no tools for tube connection. Press the release sleeve to disconnect. This saves time during installation and maintenance.

The model PA(2)-8-G01 takes 8 mm outer diameter tube and uses G 1/8" BSPP male thread. It handles working pressures up to 1.0 MPa and temperatures from −10°C to +60°C.

Key Specifications

The PA(2)-8-G01 is a 3-way rotary elbow fitting with two push-in tube ports for 8 mm OD tubing and one male G 1/8" BSPP threaded port. The body rotates 360 degrees after installation. It handles working pressures from 0 to 1.0 MPa and temperatures from −10°C to +60°C. See the full parameter table below.

Non-standard tube sizes (3, 5, 7, 9, 14, 15 mm, 1/8") and custom thread specs are available on request. Contact us for details.

Material Breakdown

How to Install

Our push-in fittings install by hand. No tools or thread sealant needed. Follow these steps to get a leak-free connection.

Step 1: Check the tube end

Cut the tube square with a tube cutter. A clean 90-degree cut gives the best seal. Do not use scissors. Inspect the end for burrs or cracks. If you see any, cut the tube again.

Step 2: Insert the tube

Push the tube straight into the port until you feel resistance. Then push harder until it seats fully. You should feel a small click as the grip ring catches the tube. The tube must go all the way in. A partial insertion will leak.

Step 3: Check the fit

Pull the tube gently to confirm the grip ring holds it. Do not twist. The tube should not move. If it comes out, push it in again until it seats.

Step 4: Adjust the rotation

For rotary models, rotate the body to the desired angle after the tube is locked. The body spins 360 degrees around the thread. This lets you route the line without kinks.

Step 5: Remove the tube

Press the elliptical release sleeve toward the body. Hold it down and pull the tube straight out. Do not twist the tube while pulling. This protects the grip ring and extends fitting life.

Tip: Our fittings come with pre-sealed threads. The gasket, O-ring, and Teflon coating are already on the thread. Do not add extra thread sealant. Overtightening may damage the gasket.

Features

• ✓One-touch push-in. Push the tube straight in. The grip ring locks it. No wrenches or thread sealant needed.

• ✓360° rotary body. Rotate the fitting after installation to adjust tube direction. This removes stress from the line.

• ✓Pre-sealed threads. Gasket, O-ring, and Teflon coating are already on the thread. Screw it in and go.

• ✓Elliptical release sleeve. One finger presses the sleeve to release the tube. Works in tight spaces where you cannot reach around the fitting.

• ✓Wide size range. Standard tube sizes 4, 6, 8, 10, 12 mm and threads M5 to R 1/2. Non-standard sizes available.

• ✓Internal hex recess. PC type fittings have a six-angle wrench pocket inside. Tighten them in confined spaces where external tools do not fit.

Model Selection Matrix

Pick your model using the format PA(2) – Tube OD – Thread. Example: PA(2)-8-G01 = 8 mm tube + G 1/8" BSPP.

BSPP (G), BSPT (R), NPT, and Metric equivalents available. Non-standard sizes (3, 5, 7, 9, 14, 15 mm, 1/8") also produced. Contact us for custom orders.

How to Select

Use these five checks to pick the right PA fitting for your system.

1. Measure tube outer diameter

   Use calipers to check the tube OD. Match it to the fitting model number. PA(2)-8-G01 fits 8 mm tube. Do not mix inch and metric sizes.

2. Check thread type and size

   Identify the port thread on your valve or cylinder. BSPP (G) is parallel, BSPT (R) is tapered, NPT is US tapered. Use a thread gauge if you are not sure. We stock all four standards.

3. Confirm pressure and temperature

   Check your system maximum pressure and ambient temperature. The PA series works from 0 to 1.0 MPa and −10°C to +60°C. For higher pressure or temperature, contact us for metal-body alternatives.

4. Check fluid type

   PA rotary fittings handle filtered air and neutral gases. Water use is conditional. For oil, chemicals, or food contact, ask us for material compatibility. FKM and EPDM seals are available.

5. Check space constraints

   If the fitting sits in a tight corner, a rotary model lets you adjust the tube angle after installation. PC type fittings have an internal hex recess for a low-profile wrench. Measure your clearance before ordering.

Applications

PA rotary fittings work in any system that needs quick tube connection and flexible routing.

Frequently Asked Questions

What is a PA rotary 3-way fitting?

A PA rotary 3-way fitting is a quick-connect pneumatic elbow. It has two push-in tube ports and one male threaded port. The body rotates 360 degrees after installation. This lets you adjust tube direction without stressing the line. We build these fittings with PA plastic housings and brass thread inserts.

What tube sizes work with PA rotary fittings?

PA rotary fittings accept tube outer diameters from 3 mm to 16 mm. Standard sizes are 4, 6, 8, 10, and 12 mm. Non-standard sizes including 3, 5, 7, 9, 14, 15 mm and 1/8 inch are also available by request.

What thread types are available on PA rotary fittings?

We offer BSPP (G), BSPT (R), NPT, and metric threads on PA rotary fittings. Male thread sizes range from M5 to R 1/2. The model PA(2)-8-G01 uses G 1/8 BSPP thread for 8 mm tube.

What is the working pressure of PA fittings?

PA rotary fittings handle working pressures from 0 to 1.0 MPa. That equals 10 bar or 145 psi. The vacuum rating is −100 kPa, which is 10 Torr or 750 mmHg.

What materials are used in PA rotary fittings?

We use PA polyamide for the body housing, brass for the thread insert, nitrile rubber (NBR) for the O-ring seal, POM acetal for the release sleeve, and 304 stainless steel for the grip ring. Brass threads get acid pickling and nickel or chrome electroplating.

How do I select the right PA fitting?

Start by measuring your tube outer diameter with calipers. Match it to the model number. PA(2)-8-G01 fits 8 mm tube. Next, identify the port thread on your valve or cylinder. BSPP (G) is parallel, BSPT (R) is tapered, NPT is US tapered. Check your system pressure and temperature. The PA series handles 0 to 1.0 MPa and -10°C to +60°C. For fluid compatibility, PA fittings handle filtered air and neutral gases. Water use is conditional. If you need oil or chemical resistance, contact us for FKM or EPDM seal options. Finally, check your space. Rotary models adjust tube angle after installation. PC types have an internal hex for tight spots.

How do I install a push-in fitting?

Cut the tube square with a tube cutter. Do not use scissors. Push the tube straight into the port until you feel it seat fully. You should feel a small click as the grip ring catches. Pull the tube gently to confirm it locks. For rotary models, rotate the body to the desired angle after the tube is locked. To remove, press the elliptical release sleeve toward the body and pull the tube straight out. Do not twist. Our fittings come with pre-sealed threads. Do not add extra thread sealant. Overtightening may damage the gasket.

How do I troubleshoot a leaking push-in fitting?

First check that the tube is fully inserted. A partial insertion is the most common cause of leaks. Pull the tube out and push it back in until it seats. Second, inspect the tube end. A crooked or cracked end will not seal. Cut the tube square and reinsert. Third, check the tube OD. If the tube is undersized, the grip ring will not hold. Use calipers to confirm. Fourth, check the thread seal. Our fittings have pre-sealed threads. If you removed the fitting and reinstalled it, the gasket may be damaged. Replace the fitting or contact us for a replacement.

Where are PA rotary fittings used?

PA rotary fittings are used in automated production lines, packaging machinery, food and beverage processing, chemical equipment, pneumatic tools, SMT and PCB equipment, robot end effectors, and medical devices. The 360-degree rotation makes them ideal for tight installations.

Do you offer OEM and custom sizes?

Yes. We produce non-standard tube sizes including 3, 5, 7, 9, 14, 15 mm and 1/8 inch. Custom thread specifications, private labeling, and bulk packaging are available. Contact us directly for OEM quotes.
