Flanged Fittings are and excellent choice for making flanged tubing conntections. They are compatible with most standard 1/4-28 or M6 Flat-Bottom ports. The hard, inert Delrin® (acetal resin) nut has been optimized to resist cross threading or loosening during use, while the TEFZEL™ (ETFE) nuts work well in chemically aggressive environments. Our fittings for 1/16 inches or 1/8 inches outer diameter tubing are supplied with a nut and a 316 stainless steel washer. There are multiple selections of head styles, materials, and colors to choose from.

Flangeless Fittings eliminate the need to flange tubing. This removable and reusable system provides several benefits such as providing flangeless chromatography fittings for observing mixtures and solvents. Flangeless Fittings are easy to use. Just slip the nut and ferrule over the tubing and finger tighten the assembly into your receiving port. Our Flangeless Fitting require minimal downtime because component replacement is quick, taking only a few seconds. Flangeless Fittings systems typically require only one new ferrule at minimal cost when repairing a connection.

Metric Flangeless Fittings offer the same benefits as our Flangeless Fittings with the additional feature of being used for metric tubing and ports. They are specifically designed to connect 1.8, 2.0, 2.5, 3.0, or 4.0 mm outer diameter tubing to flat-bottom ports when paired with the appropriate M6, 1/4-28, or 5/16-24 Flangeless Nuts. We also offer M6-threaded nuts to connect 1/16 inches or 1/8 inches outer diameter tubing, plus a tubing sleeve to facilitate 1.0 mm outer diameter tubing connections.

Our NanoPort Fittings are specifically for use with NanoPort Assemblies. These assemblies provide fluidic connections for chip-based analysis. They offers strength and consistency needed to make these connection.

Our Super Flangeless Fittings provide the highest pressure holding capability in a flat-bottom fitting system that we offer. Our unique design eliminates loosening of fittings due to tubing twist and holds tight even through vibration. Our high pressure fittings are excellent for tubing assemblies and those times when connections need to be broken frequently.

The dual compression created by the specially designed nut and ferrule enables the SealTight Fittings system to outperform standard finger tightened fittings. The forward cone of the SealTight Ferrule provides gripping power and a leak-free seal via conventional compression by the receiving port. The slotted end creates the second compression zone in conjunction with a SealTight Nut.

VacuTight Fittings are designed to provide airtight, dependable connections under vacuum and low pressure conditions. Many of the VacuTight Nuts have streamlined profiles for use in systems requiring a large number of connections in a small area. Furthermore, the VacuTight Ferrule’s small size ensures sufficient nut/thread engagement, even in shallow ports. These features make VacuTight Fittings ideal for “combichem” high throughput screening, clinical diagnostic, and other automated liquid handling applications.

Our 4 Way PEEK Valves offers three flow-path versions and biocompatible flow paths making it chemically inert and delivering excellent chemical resistance. PEEK and fluoropolymer construction yields a valve as durable as it is economical.There are Standard or Bulkhead Mount versions available. Our valves have a low swept volume and it can withstand pressures to 500 psi (34 bar).

In many applications, there is a need to limit the fluid flow to one direction. Check valves are the perfect solution for this need. Several versions are available, including our standard check valves, our non-metallic check valves, and even some specialized luer-based check valves. Check Valves are designed to effectively deliver a low cracking pressure. Most of our Check Valves connect directly to any 1/4-28 flat-bottom port. We created this unique design to eliminate the need for additional tubing cuts and connections to install traditional check valves. They accept fittings with 1/32 inches, 1/16 inches, 1/8 inches or 1.0 to 3.0 mm outer diameter tubing.

Many Injection Valves are biocompatible inert and deliver a low swept volume. Their unique design allows for minimal dispersion. Our injection valves come conveniently in both manual standard and bulkhead-mount versions. It comes with an easy to use Injection Port Adapter too. Injection Valves feature easy, external sample loop customization. Simply clean-cut a piece of tubing that represents the volume of sample you wish to inject, taking into account the port-to-port volume of the valve.

Micro-Metering Valves consistently produce fine control of fluid flow rates. When used with a tee it can reduce outgoing flow to as low as 3.5 µL/min (@ 1 mL/min incoming flow rate with room temperature water). These needle valves are perfect for use with peristaltic pump fluid-transfer applications, mass spectrometry, and fraction collection. Micro-Metering Valves can also be used to regulate gas flow in helium sparging lines and as flow-dependent variable back pressure regulators. Flow path materials are PEEK polymer (valve body, needle) and PTFE (O-rings). The fittings included with the valves are manufactured from PEEK polymer only (10-32 threaded version) and PEEK and Tefzel® (1/4-28 threaded versions). All versions of these valves have 0.020 inches thru-holes.

Our Micro-Splitter Valves are ideal for LC-MS and other multi-detector systems, fraction collectors and post column reactions. The ideal placement of these valves is on the effluent side of the detector flow cell, at a maximum pressure of 800 psi (55 bar). Or select our high pressure graduated option that can withstand a maximum pressure of 4000psi (276 bar). Choose between 1/4-28 and 10-32 threaded versions. A 10-32 / 6-32 valve is also available to accommodate applications involving capillary tubing.

Our Selection Valves are biocompatible & inert and deliver a low swept volume. Their unique design allows for minimal dispersion. Our selection valves come conveniently in both manual standard and bulkhead-mount versions. They have a pressure rating of up to 1,000 psi (69 bar). We offer two versions – one for 1/16 inches outer diameter tubing and another for 1/8 inches outer diameter tubing available in two configurations: standard manual and bulkhead-mountable manual. A valve mounting bracket is available to secure the bulkhead-mount versions to a lab bench or counter surface.

Biocompatible Shut-Off Valves effectively stop a flow stream quickly. The bodies are manufactured from either PEEK™ or Tefzel® (ETFE) with a rotor, making them highly resistant to chemical attack. Try one of our ETFE valves, which turn at a low torque and hold to 500 psi (34.5 bar). The blue colorant used in some valve configurations has proven not to leach out with most common HPLC solvents. Connect semirigid polymer tubing, such as PEEK or Fluoropolymer e.g., FEP, PFA, with the Flangeless Fittings provided. Soft tubing, such as Pharmed® or Tygon®, may be connected to these valves using our 1/4-28 barbed adapters.

Our Connector accessories are designed to supply products that are useful for your connection needs. We offer a disposable Luer-Lock Syringe that can be easily with our Adapters. We also offer mounting brackets to be used with our unions.
