Push-Fit Fittings Manufacturer — PPSU, Tool-Free & Demountable for PEX, PE-RT & Copper
Hitze push-fit fittings connect by hand — push the pipe in until it seats and it’s sealed. A PPSU body, O-ring seal and stainless grab ring make one leak-free joint on PEX, PE-RT or copper, with no press tool, no crimp, no solder and no fusion.
Sizes 16 / 20 / 25 / 32 mm. Demountable and reusable when the layout changes. Lead-free, potable-rated, with cUPC, NSF-61, DVGW, WRAS and CE + DoP certification support — no MOQ, so you can start with samples or a small trial order.
Trade & bulk supply only — Hitze does not sell single units at retail.

Connection Method
Push-Fit vs Press vs Compression — Which Connection, and When
Buyers mix these up constantly. Three connection methods, three jobs. This page covers push-fit — for the press and compression ranges, follow the links, and see our brass fittings range for threaded and compression brass connectors.
Why push-fit wins on-site: no flame, no press tool to carry, no waiting for fusion to cool — you push, it’s sealed, and you can pull it apart again if the layout changes. That’s why renovation and repair crews reach for push-fit first.
- Push-fit — tool-free, demountable; the fastest joint for renovation and wet fixes.
- Press — press-tool crimp, permanent; the go-to for concealed new-build runs.
- Compression — wrench-tightened ferrule; PE/poly mains and service points.
| Connection | How it joins | Tool needed | Reusable? | Best for | Hitze range |
|---|---|---|---|---|---|
| Push-Fit (this page) | Push pipe in — grab ring holds, O-ring seals | None — tool-free | Yes — demountable | Renovation, quick repairs, tight spaces, wet fixes | Push-Fit Fittings |
| Press | Press tool crimps a stainless sleeve | Press tool (TH/U/F/M jaw) | No — permanent | New-build, concealed permanent runs | Press Fittings → |
| Compression | Ferrule / olive + nut clamps the pipe | Wrench (hand tool) | Yes — re-tightenable | PE / poly & irrigation mains, service points | Compression Fittings → |

Material & Demount
PPSU Body, Demountable & Reusable — Built to Come Apart, Not Fall Apart
The two questions that separate a professional push-fit from a disposable one: what’s the body made of, and can you take it back off?
Hitze push-fit fittings use a PPSU (polyphenylsulfone) body — a high-performance engineering polymer chosen for hot-water and hydronic service because it resists high temperature, hydraulic stress-cracking and hydrolysis, where cheaper POM or nylon bodies embrittle and crack over time. The connection is demountable: a demount clip (or release collar) retracts the stainless grab ring so the pipe pulls straight out. Reposition it, extend the run, or reuse the fitting entirely — no cutting, no crimp to grind off. This is what makes Hitze push-fit the natural choice for renovation, repairs and any install where re-entry is expected.
How the Joint Works — Three Parts, One Push
| Part | Material | Job |
|---|---|---|
| Body | PPSU (polyphenylsulfone) | High-temp, stress-crack-resistant shell |
| Seal | O-ring (potable-rated elastomer) | Watertight seal on the pipe OD |
| Grip | Stainless-steel grab ring | Locks the pipe; releases with demount clip |
Size Matrix
16–32mm Push-Fit for PEX, PE-RT & Copper
One push-fit family that connects the three pipes a heating and plumbing wholesaler actually stocks — potable PEX, PE-RT underfloor pipe, and copper.
Hitze push-fit fittings cover 16, 20, 25 and 32 mm across the geometries you sell most — couplings, elbows, tees, reducers, stop ends and threaded transition adapters. Because a single fitting accepts PEX, PE-RT or copper, your counter carries fewer SKUs while covering potable plumbing, radiant-floor / hydronic heating pipe, and copper service lines from one range. That consolidation is exactly what a wholesaler wants: one push-fit line, three pipe systems, less split inventory.

Compliance
Potable & Lead-Free — Certified for Drinking Water
A push-fit sealing a potable line has to clear two checks: a potable-rated body and seal, and lead-free wetted metal.
Hitze push-fit fittings are built for drinking water. The PPSU body and O-ring are potable-rated, and the wetted metal parts — including the stainless grab ring — are lead-free, supporting NSF/ANSI 61 in North America and WRAS / DVGW drinking-water requirements in the UK/EU. Across the wider Hitze portfolio, our systems and fittings carry cUPC (IAPMO), NSF-14, NSF/ANSI 61, DVGW, WRAS and CE + DoP — the certification families North American and European buyers require to specify with confidence. Certificate and listing numbers are provided in the Hitze Cert Pack and are verifiable at source.
