# PLM Push-to-Connect Bulkhead Elbow Air Fitting Date: 2026-07-14 Categories: Pneumatic Fittings URL: https://homipneu.com/plm-pneumatic-bulkhead-elbow.html ## Product Summary PLM pneumatic fittings are **bulkhead elbow push-to-connect connectors** designed for 90-degree tube routing through panels in pneumatic systems. Combining a **bulkhead mounting structure with a 90° elbow design**, PLM fittings allow tubing to pass through panels while changing direction, making them ideal for compact installations and organized air line layouts. The push-to-connect mechanism enables quick tube insertion without tools, while the locking nut ensures secure panel mounting and leak-free performance. **OEM and ODM customization services are available** for tube sizes, thread standards, sealing materials, and branding requirements. ### Specification Parameters **Operating Fluid** Air **Type** Pneumatic Fittings **Proof Pressure** 1.32 MPa (13.5 kgf/cm²) **Max. Operating Pressure** 0~0.9 MPa (0~9.2 kgf/cm²) **Ambient & Fluid Temperature** 0~60°C **Applicable Tubing** PU Tube, Nylon Tube ![PLM pneumatic bulkhead elbow fitting 90 degree push to connect air connector](https://homipneu.com/wp-content/uploads/2026/04/20260428201409702916-800x440.webp) Model ØD1 ØD2 B E M H1 H2 ØP PLM-4 4 4 36.5 18 M12×1 14 14 11 PLM-6 6 6 40.5 20 M14×1 17 15 13 PLM-8 8 8 43.5 22 M16×1 19 17 15 PLM-10 10 10 48.5 26 M20 × 1 24 21 18.5 PLM-12 12 12 50.5 28 M22× 1 27 24 21 ### Key Features - 90° elbow + bulkhead combined structure - Tube routing through panel with direction change - Push-to-connect quick installation - Secure panel mounting with locking nut - Leak-proof sealing with O-ring ### Applications - Pneumatic control panels - Industrial automation systems - Air distribution pipelines - Machinery equipment - Robotics and assembly lines Widely used in pneumatic systems requiring **panel-through installation, 90-degree tube routing, and compact layout optimization**. ### Product Function PLM fittings are designed to **route pneumatic tubing through panels while simultaneously changing direction by 90°**, reducing the need for additional fittings and simplifying system layout. 👉 Simple comparison: - PC = straight male fitting - PM = bulkhead straight union - PL = elbow fitting - **PLM = bulkhead + elbow (combined function)** 👉 Elbow fittings are commonly used to connect pipes at angles (e.g., 90°) in fluid or air systems ### Product Structure & Size Range - PLM4 / PLM6 / PLM8 / PLM10 / PLM12 - Tube sizes: 4mm → 12mm - Panel mount with locking nut - 90° elbow connection ### Why Choose Our Pneumatic Fittings - Professional **PLM pneumatic fitting manufacturer** with full size range - OEM / ODM customization for **bulkhead elbow push to connect fitting projects** - Reliable **pneumatic elbow connector for panel-mounted air systems** - High-quality **push-in air fitting factory China with strict QC system** - Durable **90° bulkhead pneumatic fitting for compact installations** - Fast delivery and global B2B supply support ### FAQ **Q1: What is a PLM pneumatic fitting?**It is a bulkhead elbow push-to-connect fitting used to route tubing through panels at a 90-degree angle. **Q2: What is the advantage of a bulkhead elbow fitting?**It combines panel mounting and direction change, reducing installation complexity. **Q3: What is the difference between PM and PLM fittings?**PM is a straight bulkhead fitting, while PLM is a bulkhead elbow fitting. **Q4: What tubing is compatible with PLM fittings?**They are compatible with PU tube and nylon tube. **Q5: Can PLM fittings be customized?**Yes, OEM/ODM customization is available for size, material, and design.
