Pneumatic

Thread reducing adapter (bushing) from 1/2" NPT to 1/8" NPT. Features a 1/2"-14 NPT female port and a 1/8"-27 NPT male thread. Typically made of 304 stainless steel for high strength and corrosion resistance. Allows attaching small 1/8" NPT fittings (such as pressure sensors or gauges) into 1/2" NPT ports. Useful in pneumatic/hydraulic systems to adapt port sizes.

Brass reducing coupler with 1/2" female NPT and 1/4" female NPT ends. Allows connection between a 1/2" NPT male fitting and a 1/4" NPT male fitting. Often used to step down pipe size in pneumatic, fuel, or hydraulic systems. Sturdy brass construction suitable for water, oil, gas (WOG) applications up to ~1000 PSI.

Brass thread adapter for connecting G1/2 BSP parallel threaded components to 1/2" NPT threaded components. Features a female G1/2-14 BSPP port (with rubber washer for sealing) and a male 1/2"-14 NPT taper thread. Useful for linking European/Asian (BSP) pneumatic parts with US standard (NPT) piping. No official datasheet; typical use in pneumatic systems up to ~500 PSI.

Compact pneumatic silencer (muffler) with 1/4" NPT male thread. Attaches to exhaust ports of valves or cylinders to reduce noise and filter out particles. SMC AN series (AN20-N02) features a sintered metal or polymer element that allows air to vent quietly to atmosphere.

SMC KQ2 series one-touch fitting with a female threaded port. Connects a 1/8" NPT male thread to a 1/4" OD push-in tube. Model KQ2F07-34N provides a compact way to attach a small NPT-threaded component (like a pressure sensor or gauge) into a 1/4" tubing line.

SMC KQ2 series straight one-touch fitting. Connects a 1/4" OD pneumatic tube to a 1/4" NPT threaded port. Male thread is 1/4"-18 NPT (likely no sealant on this model), and the push-in end accepts 1/4" (6.35 mm) outer diameter tubing. Commonly used for quick connection of air lines to valves, manifolds, or cylinders.

SMC KQ2 series straight fitting for 3/8" OD tubing with a male 1/4" NPT thread. Model KQ2S11-35NS has a hex socket head design and comes with thread sealant pre-applied for easy installation. It allows a 3/8 inch pneumatic tube to be directly connected to a component with a 1/4" NPT female port.

SMC KQ2 series union tee fitting for 1/4" OD tubing. A three-way push-to-connect fitting that splits or combines flow between three 1/4" pneumatic tubes at a T-junction. Ideal for branching an air supply line into two lines or vice versa. All three ports accept 1/4" outer diameter tube.

SMC KQ2 series union cross fitting for 1/4" OD tubing. A four-way push-to-connect fitting that joins four 1/4" tube lines at a single intersection, allowing one inlet to supply three outlets or interconnection of four lines. All ports accept 1/4" outer diameter tubing, forming a plus-shaped junction.

SMC TIA series general-purpose pneumatic tubing, 1/4 inch (6.35 mm) outer diameter. Made of nylon (polyamide 12) for durability and pressure resistance. Provided typically in a 33-meter roll (part code -33). Suitable for air or water lines up to ~1.5 MPa (217 psi) at room temperature. Commonly colored orange (for easy identification).
