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 Fittings Tools are designed to assist you with your connections. Our Extender Tools are excellent choices to aid it the imperative tightening process. can be used to tighten most of our knurled nuts in hard to reach places. For precise tightening, the extender tools listed with 1/4 inches hex drives are designed to adapt to any torque wrench with a female 1/4 inches socket, such as the VHP-4000 Torque Driver. Our durable wrenches are slotted to fit over 1/16 inches and 1/8 inches outer diameter tubing, and have 1/4 inches and 5/16 inches internal hex ends. Our wrench is designed to engage with the heads of the hex-head fittings most commonly used with our valves and stainless steel fittings. For your convenience, we offer wrenches in three easy to use standard sizes. Our tools also feature FlushNut™ wrenches, used to tighten the FlushNuts. Our Removal Tools are specifically designed to detach LiteTouch® and Super Flangeless™ Ferrules from tubing. Simply slide the appropriate tool blade slot between the lock ring and the ferrule body. With a slight twist, the ring will pop off, releasing the ferrule from the tubing. Please Note: This Removal Tool will not work with the LT-135 Ferrule System.

Large Bore Flangeless Fittings eliminate the need to flange tubing. This removable and reusable system provides several benefits. 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 Large Bore Flangeless Fittings are specifically designed to work with 5/16-24 & ½-20 threaded fittings. Flangeless Fitting require minimal downtime because component replacement is quick, taking only a few seconds. Flangeless Fittings system typically requires only one new ferrule at minimal cost when repairing a connection.

Our Caps are offered in biocompatible PEEK or Tefzel® (ETFE) giving them excellent chemical resistance. Our caps are designed to effectively cap and seal off tubing.

Our plugs are designed to optimally close off unused ports in valves and multi-port connectors. Our color-coded 10-32 threaded plugs are perfect for identifying stored columns that have different packing materials, or in which different mobile phases have been utilized.

Our NanoTight kits allow you to easily connect capillary tubing to standard 1/16 inches ports. Our NanoTight Kits are carefully manufactured using Dupont® FEP fluoropolymer – a highly inert, melt-processed polymer that serves as an excellent alternative to PTFE. Our kit is designed to increase flexibility and convenience at a lower per-piece price than if the components were purchased separately.

Our Polymer Tubing Kits are optimally designed for use in high-pressure applications. Our PEEK tubing kits include our distinct PEEK tubing which is inert to most solvents and give it a smooth internal surface that improves the resolution of sample bands. We have developed a variety of color options for easy coding and identification. Our Tefzel (ETFE) tubing kits provides tubing that is designed with three of the most common inner diameters and its unique material provides low gas permeability.

Our FEP tubing sleeves are an excellent choice for lower pressure applications. These 1.6 inches long sleeves facilitate connecting capillary tubing into ports designed for 1/32 inches outer diameter tubing. We offer a wide selection of appropriate sleeve for your capillary outer diameter size. These sleeves can be used at up to 50 ºC and have a pressure rating of 1,750 psi (121 bar).

Our 1/32 inches outer diameter PEEK Tubing Sleeves is designed to be used with any fitting made for 1/32 inches outer diameter tubing when smaller tubing must be connected. It is 1.6 inches in length. Select the appropriate sleeve from the product listing for your capillary tubing OD size. The 1/32 inches outer diameter PEEK Tubing Sleeves have a maximum recommended temperature of 125 ºC and have a pressure rating of 5,000 psi (345 bar).

NanoTight Tubing Sleeves are manufactured using versatile Dupont® FEP and are precisely cut to a 1.6 inches length. We offer a wide assortment of sleeves ensuring availability for most applications. Many of the sleeves feature a light color tint that can help more easily identify the inner diameter for future orders. Because FEP is the base polymer for these sleeves, there is a maximum recommended continuous operating temperature of 50 ºC.

Our ETFE Tubing constructed with Tefzel™ ETFE resin is chemically inert and delivers excellent solvent resistance. It offers a structure that is more rigid than PTFE, FEP, and PFA making this tubing better able to resist inner diameter collapse. This material delivers more durability and is less gas permeable. It has operating temperatures of up to 80°C.
