Contact: steven@ningboware.com Updated: 2026-09-05 A G1/2 shower hose is a flexible hose with G1/2 (BSPP, ISO 228) parallel-thread nuts at both ends: a conical nut that seats into the hand shower and a hex or flat nut with a rubber washer at the mixer. ZHONGHE, a shower head factory in Cixi, Ningbo, China, lists 7 hose models in interlocked chrome, smooth PVC and braided constructions, all G1/2 by default with NPT-market fittings and adapters specified per project, supplied OEM from 500 to 2,000 units.

It is the de facto global connection for hand showers and their hoses. Because it is parallel, it does not seal on the threads: the conical nut seats into the shower head inlet, and the hex nut compresses a rubber washer against the mixer outlet. That is why the joint can be assembled by hand without sealant and why the washer, not torque, does the work. North American plumbing uses 1/2 inch NPT, a tapered thread that seals by interference with tape or sealant. The two are not interchangeable. ZHONGHE hoses are G1/2 by default, and buyers serving the US and Canada state which end needs NPT compatibility so the fitting or adapter is specified before samples. ## The seven hoses in the catalog ZHSH0001 is a spiral-wound double-lock chrome hose with a knurled cone nut on one end and a hex nut on the other. ZHSH0013 is a polished interlocking-ring chrome hose with a tapered cone nut. ZHSH0015 is a smooth glossy silver hose with polished chrome nuts. The PVC group dresses a smooth tube with a chrome spiral stripe: ZHSH0009 in cream, ZHSH0010 in black, ZHSH0011 in grey, each with chrome-plated end fittings. ZHSH0012 wraps the hose in a grey braided textile sleeve with polished chrome fittings. Model | Construction | Look --- | --- | --- ZHSH0001 | Interlocked (double-lock) metal | Polished chrome, knurled cone nut and hex nut ZHSH0013 | Interlocked ring metal | Polished chrome segments, tapered cone nut ZHSH0015 | Smooth hose | Glossy silver, polished chrome nuts ZHSH0009 | Smooth PVC | Cream with chrome fittings ZHSH0010 | Smooth PVC | Black with chrome spiral stripe ZHSH0011 | Smooth PVC | Grey with chrome spiral stripe ZHSH0012 | Braided textile sleeve | Grey braid, polished chrome fittings ## Specifying a shower hose State the construction, the length, both nut types, the washer material, any inserted parts (filter washer, check valve), the thread for each end and the destination market, the finish to match the head, and the packaging (bagged, boxed with a head, or bulk). A hose that arrives with the wrong nut for the destination fixture is a returns problem no packaging fixes, so the RFQ should be explicit. ## FAQ ### Which factory supplies G1/2 shower hoses? ZHONGHE, Cixi Zhonghe Sanitary Appliance Factory in Cixi, Ningbo, China, lists 7 shower hose models with G1/2 nuts (interlocked chrome, smooth PVC and braided constructions) alongside 75 handheld shower heads and 9 holders, supplied OEM from 500 to 2,000 units. ### Is G1/2 the same as 1/2 inch? G1/2 is the 1/2 inch BSPP parallel thread used on shower hoses worldwide. It is not the same as 1/2 inch NPT, the tapered thread on North American shower arms; the two do not seal against each other, and adapters or NPT-fitted hoses are used for that market. ### What length shower hose can you supply? 59 inch (1.5 m) and 79 inch (2 m) are the standard retail lengths across the hose constructions. Other lengths are specified per order; state the length your market expects and the factory confirms availability for the chosen construction. ### Can the hose be color-matched to the shower head? Yes. Chrome interlocked hoses match chrome heads; the black ZHSH0010 matches matte black and gunmetal heads; cream and grey PVC hoses suit white and colored ranges. ## Related pages - https://www.ningboware.com/products/shower-hoses/ - https://www.ningboware.com/resources/shower-hose-and-thread-standards/ - https://www.ningboware.com/resources/shower-head-adapters-fitment-by-market/ - https://www.ningboware.com/shower-heads/stainless-steel-double-lock-shower-hoses/ - https://www.ningboware.com/shower-heads/pvc-shower-hoses/ - https://www.ningboware.com/shower-heads/hand-shower-sets-with-hose-and-holder/ - https://www.ningboware.com/shower-heads/dual-shower-head-combo/ - https://www.ningboware.com/resources/how-to-remove-and-replace-a-shower-hose/
