DISTRIBUTOR-FIRST SUPPLY PARTNER · SINCE 1999 BRAND · THB
Reliable Taiwanese FRLs, couplers, and fittings for industrial pneumatics.
Control. Connect. Flow.
THB Enterprise Co., Ltd. (Hui Bao Enterprise Co., Ltd.) has manufactured pneumatic components in Changhua County, Taiwan since 1988.
The company built its reputation on FRL combinations, quick couplers, and brass fittings — the workhorse components that condition and connect compressed air at the point of use. A 95% self-production rate keeps quality in-house from raw material through finished assembly.
THB covers the full air-prep spectrum in a single catalog: filter-regulator-lubricator units from 1/8" through 1" NPT, quick couplers in Japanese, European, American, and stainless-steel body styles, swivel fittings, hose fittings, and pneumatic accessories. Couplers are durability-tested to 100,000 cycles and meet NFPA/T3.20.14 standard. The line is positioned as a proven, cost-competitive Taiwanese alternative to premium European FRL and coupler brands for general industrial plant air conditioning.
THB moves through SPC's distribution network, so lead times stay short and order minimums stay reasonable for smaller top-off purchases alongside larger line items.
Not every air-prep job needs a premium European FRL.
SPC pairs THB FRL components with upstream treatment and downstream pneumatic controls across the same order, keeping the bill of materials tight and the service relationship with one contact.
General Manufacturing → Primary market — general plant air prep with FRLs and couplers at maintenance points. 
Automotive Manufacturing → Pneumatic tool connections and air-line conditioning on assembly lines. 
Metalworking & Fabrication → Air-prep components for pneumatic tooling and surface finishing. 
Packaging & Printing → Pneumatic conditioning for pneumatic actuators and air-powered packaging equipment. 
Food & Beverage Processing → Stainless-steel coupler options for wash-down and hygienic connection points 
Construction & Infrastructure → Couplers and hose fittings for portable and jobsite compressed-air tools. THB FRL and coupler lines span 1/8" through 1" NPT. Match port size to the downstream tool or actuator flow requirement — undersizing a regulator port costs pressure and performance at the point of use.
Japanese (Nitto-style), European, and American Industrial types are not interchangeable. Confirm the plug/nipple style already in the plant before specifying a coupler body — THB offers all three plus stainless steel for corrosive environments.
Combined FRL units simplify installation where filter, regulator, and lubricator are all needed. Specify individual components where only one or two functions are required, or where servicing independently is preferred.
