AUTHORIZED PARTNER
Parker Chomerics Thermal interface materials and liquid-cooling connectivity
From THERM-A-GAP pads to fire-rated cooling hoses and non-spill quick disconnects. HeTone is the authorized distributor across Asia, providing selection support, inventory, application engineering, and in-house hose assembly.
Brand Overview
Parker Chomerics, a division of Parker Hannifin, has led the thermal interface material (TIM) market for over four decades. Their THERM-A-GAP, CHO-THERM, and T-FLEX product families are the industry standard for moving heat from semiconductors to heatsinks in applications from consumer electronics to defence-grade systems.
As an authorized distributor, HeTone provides the full Parker Chomerics portfolio with local inventory in Taiwan, technical pre-sales support, and qualification assistance. We help engineers select the right TIM for their gap, thermal resistance, and compression-force requirements, from prototype samples through volume production.
The partnership now spans the full liquid-cooling flow path: UL94 V-0 rated thermal management hoses, non-spill quick disconnects up to blind-mate rack systems, push-in fittings, and process valves from the Parker Hose Products and Quick Coupling divisions. In Taiwan, HeTone cuts, crimps, cleans, and leak-tests hose assemblies to ISO 16232 cleanliness in a class 100K clean room, delivering ready-to-install kits for data-center and industrial cooling loops.
Product Series
Featured product families.
CHO-THERM® Insulators
Electrically isolating thermal pads with dielectric strength up to 4 kV. Ideal for power modules, MOSFETs, and any interface where thermal transfer and electrical isolation must coexist.
Up to 4 kV isolationT-FLEX™ Series
Highly conformable gap fillers for uneven surfaces and large gaps. Excellent wetting and surface contact without the mess of thermal grease. Reworkable and reusable.
Highly conformableThermal Management Hoses
Fire-rated EPDM hoses for data-center liquid cooling: 801TM and 807 Push-Lok with UL94 V-0 covers, the 629 Server Blade hose for rack manifolds, and E-Z Form hoses for tight routing and large-bore facility lines.
UL94 V-0 ratedQuick Disconnect Couplings
Non-spill dry-break couplings from DN 3 to DN 25 in brass, stainless, and aluminium: NSI, NSP, NSG, NSE, and CDT series, plus Intel-compatible UQD and blind-mate NSEC systems for server racks.
Non-spill, DN 3-25Valves and Fittings
LF series push-in fittings including 316L stainless LF3800, hose barbs and 82 series fittings, plus stainless check valves, filter check valves, and RL4 relief valves to protect and complete the cooling loop.

A closer look.
Fire-rated hoses built for liquid cooling.
Parker thermal management hoses move DI water and glycol coolants through data centers safely: fire-retardant covers carry UL94 V-0 ratings, with temperature ratings from -40 C to 100 C across the family.
- 801TM and 807 Push-Lok with UL94 V-0 covers
- 629 Server Blade hose for direct liquid cooling racks
- E-Z Form hoses for tight routing and large-bore mains
Non-spill couplings, rack to cold plate.
Dry-break quick disconnects let servers and cooling loops be serviced without spillage: ball-locking mechanisms, low pressure drop, and body and seal options that match glycols, heat-transfer oils, esters, and deionized water.
- NSI, NSP, NSG, NSE, and CDT series, DN 3 to DN 25
- Brass, stainless steel, and lightweight aluminium bodies
- One-hand push-to-connect versions available
Intel UQD compatible, OCP ready.
For standardized server cooling, Parker UQD and UQDB couplings interchange fully with other Intel-approved UQD suppliers, while the CDT series covers the OCP-defined LQC interface at DN 25 for rack manifolds.
- UQD02 / UQD04 / UQD06 and UQDB04 sizes
- Push-to-connect, non-spill operation
- NSEC1001 blind-mate accepts 1 mm misalignment at 100 LPM
Fittings and valves that complete the loop.
Beyond hose and couplings, HeTone supplies the Parker connection hardware around them: push-in fittings up to 316L stainless for corrosive or high-purity fluids, plus check, filter-check, and relief valves for flow protection.
- LF3000, LF3600, LF3800, and LIQUIfit push-in families
- C and CBF series stainless check valves
- RL4 relief valves with field-selectable spring ranges
Assembled, cleaned, and tested in Taiwan.
HeTone builds Parker hose assemblies locally: automated cutting, crimping, and clamping, ISO 16232 cleanliness processing in a class 100K clean room, and helium, nitrogen, or water leakage testing on every assembly line.
- Cut, crimp, and clamp from 1/4 to 3 inch hose
- ISO 16232 cleaning with 100K clean room
- He / N2 / water leak testing and pull testing
