15mm 45 degree elbow compression & 45 degree bend for pipe | Factory

23% of service callbacks

trace directly to poorly machined olives and inconsistent seat surfaces in imported compression elbows. Every callback costs £85–£140 in labour alone.

±3° deviation = pipe stress

Incorrectly formed 45° elbows introduce bending stress at joints, shortening system lifespan by up to 40% in vibration-prone environments.

✅ Our 15mm 45 Degree Elbow Compression: Engineered to Outperform

Produced in our Cangzhou factory under ISO 9001 processes, our 15mm 45 degree elbow compression fitting is not just a piece of brass — it is a precision hydraulic component. Every batch is CNC-machined, degreased, pressure-tested, and traceable via laser-etch codes.

• ⚙️ CNC-machined seat surface: Ra ≤ 1.6 μm for a perfect olive seal

• 🔩 Annealed copper olives: softer than the pipe — never the reverse

• 🔒 DZR brass available: CW602N for potable water in aggressive environments

• 📏 Dimensional tolerance: angle ±1°, threads per EN 10226

• 🧪 100% pressure-tested: 16 bar water / 25 bar gas on every batch

• 🏷️ Laser-etched batch codes: full material traceability

Potable Water Systems

Ideal for residential and commercial plumbing where quick, solder-free jointing is required. CW602N grade complies with NSF/ANSI 61 and WRAS.

Heating & Radiator Circuits

Runs at up to 80°C continuous with 16 bar working pressure. The 45° angle lets you route pipes around obstacles without excessive stress.

Gas Distribution Lines

Each fitting is helium-leak tested when specified for gas. Certified to UNI 7129 / BS 864-2 for natural gas and LPG.

Compressed Air Systems

15mm compression elbows handle 10 bar industrial compressed air with ease, providing a rapid alternative to threaded steel pipe.

Q1: What is the difference between a 15mm 45 degree elbow compression and a solder elbow?

A compression elbow uses a threaded nut and an olive (ferrule) that physically compresses onto the pipe to form a seal — no heat, no solder, no flux. This makes it ideal for applications where hot works are restricted (e.g., occupied buildings, flammable environments). A solder elbow requires a torch and is permanent; compression fittings can be disassembled and reused.

Q2: Can I use these compression elbows for natural gas?

Yes. Our 15mm 45 degree elbow compression fittings are available with gas-rated certification (UNI 7129 / BS 864-2). For gas applications, we recommend the CW602N DZR brass grade with a helium leak test per fitting. Please specify "gas grade" on your RFQ so we add the proper test documentation.

Q3: Do you support OEM / private label packaging?

Absolutely. We offer OEM/ODM services: your logo on fittings, custom blister packs, retail boxes, or bulk cartons. The minimum order for custom packaging is 500 pieces per SKU, and our in-house design team provides free artwork support.

Q4: What is your minimum order quantity (MOQ)?

For stock items (standard 15mm 45 degree elbow compression in CW617N, nickel-plated), the MOQ is 200 pieces. For DZR brass or custom finishes, MOQ is 1,000 pieces. Samples (up to 5 pieces) are always available at cost, refundable with your first order.

Q5: What shipping methods do you offer for USA / Europe?

We ship via sea (20–30 days), sea-air combo (12–18 days), and air express (5–8 days) depending on your timeline. For large-volume orders, FOB/CIF/DDP terms are available. Our logistics team provides real-time tracking updates via WhatsApp or email.

Q6: Which payment methods do you accept?

Wire transfer (T/T), Letter of Credit (L/C) for large orders, PayPal for samples and small orders, and Western Union. For repeat customers, net 30 terms may be available after 3 orders.

Q7: How do I verify the quality before placing a bulk order?

First, request free samples and test them on your line. Second, we can arrange a video call with our QC team for a live inspection. Third, for orders over $5,000, a third-party inspection (SGS, BV, TÜV) can be arranged at cost.

Q8: What is the tolerance on the 45° angle?

We hold a dimensional tolerance of ±1° on the 45° angle. This is verified using a CMM on every production batch. If you need a tighter tolerance for precision applications, please let us know — we can achieve ±0.5° on request.
