GENTLE TLL Mini Long Elbow Coupler｜Extended Reach Pneumatic Fitting

• Extended-Neck Body + Hex Wrenching: The elongated body above the thread with wrench flats enables firm seating and orientation in recessed or obstructed spots.
• Clean 90° Corner Routing: Optimized bend geometry keeps right-angle turns smooth, minimizing interference, kinks, and pressure loss.
• Push-to-Connect, Fast Service: Insert fully to the stop to lock; press the release ring for quick, tool-free tube removal.
• Pre-Sealed Threads: M3/M5/M6/RC1/8–RC1/2 (BSPT) ship with sealant; PTFE tape is typically unnecessary unless the layer has been worn by repeated servicing.
• Airtight & Vibration-Resistant: Metal collet + O-ring sealing deliver reliable performance within 0–0.9 MPa, 5–60 °C.
• Compact Profile, Full Range: About 40% smaller / 20% slimmer, supporting 4–12 mm PU/nylon tubes; black or grey-white (-GW) for easy line ID.
• Applications: Deep panels and corners, near valve islands/manifolds, robot-wrist jumpers, fixture grooves, in-cabinet 90° turns, and tight corner links between modules.

Q1: How does TLL differ from TL and UL?
A: TLL = Long elbow: push-in + male thread with an extended neck body above the threads, for recessed/tight spots. TL = Standard elbow: push-in + male thread, standard length. UL = Union elbow: push-in on both ends, no thread—tube-to-tube 90° turn.

Q2: What tube sizes and thread options are available?
A: Tubes 4, 6, 8, 10, 12 mm; threads M3, M5, M6, RC1/8–RC1/2 (BSPT); grey-white variant uses -GW suffix.

Q3: Are the threads pre-sealed? Is PTFE tape required?
A: RC threads are factory pre-sealed, so tape is typically unnecessary. After many re-tightening cycles, re-seal or replace as needed.

Q4: Which tubing materials are supported? Will it slip?
A: Compatible with PU and nylon (PA). The push-in metal collet grips firmly and the O-ring seals; press the collet to release and re-cut worn tube ends before re-insertion.

Q5: What are the operating limits?
A: 0–0.9 MPa, 5–60 °C for general industrial service; verify compatibility for vacuum or special media.

Q6: What's the practical benefit of the "long" version?
A: The extended neck body bridges panel thickness, clears obstructions, and reaches recessed points while keeping a compact 90° routing.

Q7: Any installation tips?
A: Tighten the threaded end first to proper orientation/torque → square-cut with a PU tube cutter → push fully to the stop → perform a pull test → leak-test at working pressure.

Q8: Any functional difference between black and grey-white (-GW)?
A: No—only appearance, useful for machine styling and line color coding.

Q9: When to choose TLL over Y-type splitters (TBY/UY)?
A: Pick TLL for a 90° turn in a recessed/tight location; choose Y-type when you need to split one line into two.
