NAFLON™ HOSE

TOMBO™ No. 9065/9066/9067/9068

NAFLON HOSE contains an inner hose made from an excellent heat- and chemical-resistant fluoropolymer. These products can be further modified to meet the requirements of particular applications by reinforcing the outside of the tube with protective stainless steel wire braiding or fitting with designated metal or flared connections. For its main applications, it is best suited as a pipe joint for steam, oil (particularly non-flammable oils), various gases, chemical solutions, and foodstuff.

Fluoropolymer lined valve

The Ball Valve, Diaphragm Valve, and Ball Check Valve have thickly lined walls made of PFA and ETFE. The wetted part of all these products is lined entirely with fluororesin and so they can be used with peace of mind as fully-fledged, corrosion-resistant valves.

PFA lined pipes

A straight pipe fitting that has a thick wall lining made of PFA. The standard product size is 15 A to 300 A, and for straight pipes, Nichias can manufacture a product up to 5 meters. Proud of its vast lineup, Nichias has a whole range of fittings ready and available. Nichias also manufactures non-adhesive, colored PFA lining products for use with high-purity chemical solutions.

Vessel accessory

As accessories for vessels and towers that require corrosion resistance, such as fluororesin-lined tanks, glass-lined tanks, and FRP tanks, Nichias has a lineup of various products that include PFA-lined blow pipes, spargers, drip pipes, level gauges (for low pressures and for high pressures), thermometer protection tubes.

ETFE/PFA ROTO LINING

TOMBO™ No. 9966/9946

ETFE/PFA ROTO LINING is a product that is made by bonding ETFE/PFA to a metal surface through rotational molding.
It is possible to add a joint-free lining to a base material with a complex shape. However, it cannot be used for high-purity chemicals.

NAFLON™ COATING

TOMBO™ No. 9035

NAFLON COATING is a fluororesin baking paint to give fluororesin attributes such as non-stickiness and corrosion resistance to a surface such as metal. Nichias selects and installs various fluororesin materials to suit your objective and application.

CHEMICAL GUARD

TOMBO™ No. 8803-HC/-HA/-HT

It is a filter that removes low-concentration gas (ammonia and acidic and organic gases), making it suitable for the likes of clean rooms and semiconductor manufacturing equipment. By applying Nichias’ exclusive honeycomb manufacturing technologies and having a large amount of adsorbent/functional material inside the wall, it can remove ultra-low-concentration (a few μg/m3) gas components with high efficiency.

EXCELIDE™

TOMBO™ No. 9550

It is a sliding material with improved mechanical attributes such as wear resistance and creep resistance achieved by adding various filler materials to high-performance resins (PTFE, PPS) that have excellent heat resistance and low wear resistance properties.
