1. EKWB ZMT hose
K ZMT (Zero Maintenance Tubing) is a high-quality, maintenance-free industrial EPDM rubber hose in stylish matte black.
This hose is designed to withstand harsh conditions over a very long period and offers exceptional durability even under UV, ozone, and heat exposure.
Unlike most PVC and PUR hoses, this premium EK rubber hose made of EPDM ensures long-lasting operation and does not suffer from plasticizer leaching, which can lead to blockages in your liquid cooling circuit. This 9.5/15.9 mm (ID/OD) hose also allows for very tight bending radii.
This may not be the hose for everyone, but it guarantees trouble-free operation, even in the long term, which other PVC/PUR hoses cannot offer.
This hose is the perfect companion for the series 10/16 clamp fittings from EK-ACF Fitting.

2. EKWB EK-Tube ZMT hose 16/12 mm
With the EK-Tube ZMT, the traditional Slovenian manufacturer EK Water Blocks presents its own water cooling tube, manufactured according to its own ideas of perfect tubing that brilliantly fulfils the very special requirements of long-lasting, highly potent water cooling. "ZMT" stands for "Zero Maintenance Tubing", i.e. absolutely maintenance-free. The EK tube, which is offered here with a diameter of 16/12 mm, is a stylish matt black EPDM rubber tube that offers high industrial quality.
This hose is manufactured by EK Water Blocks to withstand the harshest conditions over long periods of time, unlike neoprene hoses. It offers a truly outstanding service life, even when exposed to UV, ozone or heat for several years.
In contrast to plastic products made of PVC or PUR, the EPDM rubber of the EK-Tube ZMT does not run the risk of plasticisers being washed out over the long term, which then slag the cooling circuit and reduce the effective cooling performance. In addition, the EPDM rubber used here also allows very tight bending radii thanks to its elasticity and stability. The hose offered here is black and has an outer diameter of 16 mm and an inner diameter of 12 mm.
Note: This is a 3 metre long piece of hose that is supplied in retail packaging.
