Stainless Steel Pipe Clamp Mount Support Brackets — Wall Fixing Base Fittings

Match the clamp size to your pipe's outer diameter (OD) — not the nominal pipe size. For example, a 20mm clamp fits a pipe with a 20mm OD. For range-style clamps (e.g., 20–22mm), the bracket accommodates pipes within that span.

Quick reference: 1/2" copper pipe is typically around 15–16mm OD; 3/4" copper is generally around 20–22mm OD; 1" copper is typically around 28mm OD. Always measure with calipers when in doubt.

A2 (304 grade) is suitable for most indoor and sheltered outdoor applications — plumbing, HVAC, general construction. A4 (316 grade) adds molybdenum for superior resistance to chlorides and salt spray, making it the right choice for coastal buildings, marine installations, or environments with chemical exposure. For standard indoor use, A2 is generally sufficient and more cost-effective.

Yes. Both A2 and A4 stainless steel grades provide corrosion resistance for outdoor use. For standard outdoor environments (gardens, building exteriors, sheltered eaves), A2 typically performs well. For coastal, marine, or high-humidity chemical environments, A4 is generally recommended for longer service life without surface rust.

These wall-mount pipe clamp brackets are generally compatible with copper, PVC, CPVC, steel, stainless steel pipe, and electrical conduit of matching outer diameter. The saddle design cradles the pipe without damaging the surface. For soft plastic tubing, verify the clamp does not over-compress the pipe wall when tightened.

Load capacity depends on the pipe size, wall substrate, and the fasteners used to anchor the bracket. These brackets are designed for standard pipe support and fixing in plumbing, HVAC, and conduit applications. For heavy-duty, high-vibration, or seismic installations, consult a qualified engineer and use wall anchors rated for your specific load and substrate.

Wall mounting hardware is not included. Use fasteners appropriate for your wall type: masonry anchors for concrete or brick walls, wood screws for timber stud walls, and toggle bolts for drywall without studs. Fastener diameter is typically M4–M6 — contact us to confirm the exact hole size for your selected variant before purchasing anchors.

Fixed-size clamps (e.g., 16mm, 20mm, 25mm) are designed for a single pipe OD and provide a snug, precise fit — ideal when you know your exact pipe size. Range-size clamps (e.g., 16–18mm, 20–22mm) use a slightly wider saddle to accommodate pipes within that diameter span, which is useful for flexible tubing or when pipe OD varies slightly between manufacturers.

Spacing depends on pipe material, diameter, and the fluid or load carried. As a general guideline, copper and steel pipes are typically supported every 4–6 feet (1.2–1.8m) for horizontal runs, and every 8–10 feet (2.4–3m) for vertical runs. PVC and CPVC generally require closer spacing — typically every 3–4 feet (0.9–1.2m). Always follow local plumbing codes for your specific application.
