BUC, BUL, BLM & BUG Series: The Standard for High-Performance Pneumatic Connections
Our range of BUC, BUL, BLM, and BUG series one-touch fittings is engineered for rapid, tool-free installation in compressed air systems. These Push-to-Connect fittings are the essential choice for modern automation, providing leak-proof performance and exceptional durability across a wide range of industrial applications.
Series Breakdown & Functional Overview
BUC Series (Union Straight Hand Valve): A specialized union straight fitting integrated with a manual shut-off valve. This allows operators to isolate specific sections of a pneumatic circuit for maintenance without depressurizing the entire system.
BUL Series (Union Elbow): A high-precision 90-degree elbow connector designed to change tubing direction in tight spaces. Its compact profile minimizes the footprint of pneumatic manifolds and machine frames.
BLM Series (Bulkhead Union): Designed for passing pneumatic lines through panels or bulkheads. The threaded body and lock-nut ensure a secure, vibration-resistant mount on any flat surface.
BUG Series (Triple Union / Manifold): A multi-way manifold fitting that allows for the distribution of a single air source to multiple lines (often featuring reducing port sizes). Perfect for compact air distribution in robotic end-effectors.
Technical Features & Engineering Highlights
Instant One-Touch Connection: Simply push the tubing into the fitting for an immediate, secure, and leak-proof seal. No tools or specialized training required.
High-Quality Materials: Manufactured with a high-strength PBT (Polybutylene Terephthalate) body and nickel-plated brass components for superior corrosion and wear resistance.
Secure Gripping Mechanism: Features a stainless steel collect that provides a firm grip on PU, Polyurethane, and Nylon tubing, preventing accidental disconnection under high pressure.
360° Swivel Design (Elbows): The body of elbow and manifold fittings can rotate 360 degrees even after installation, allowing for perfect tubing alignment.
Tapered Threads with Sealant: All male threads are pre-coated with Teflon sealant (or O-ring equipped) to ensure a perfect seal without the need for additional tape.
