SS304 BSP Female Thread Pipe Fittings — Reliable Connections from 1/4" to 2"

Leaking joints and mismatched threads are among the most frustrating problems in any plumbing, irrigation, or fluid-transfer project. Whether you're a plumber, HVAC technician, or serious DIYer, having the right stainless steel BSP female thread pipe fittings on hand means the difference between a clean, leak-free installation and a costly callback. These fittings are built for professionals and home builders who need dependable hardware that won't corrode, seize, or fail under pressure.

Each fitting is machined from Stainless Steel 304 (18-8 grade), offering a strong balance of corrosion resistance and mechanical strength. The female BSP (British Standard Pipe) thread is precision-cut to ensure consistent engagement with standard BSP male counterparts. Available in eight sizes — 1/4" (≈6.4mm), 3/8" (≈9.5mm), 1/2" (≈12.7mm), 3/4" (≈19.1mm), 1" (≈25.4mm), 1-1/4" (≈31.8mm), 1-1/2" (≈38.1mm), and 2" (≈50.8mm) — and sold in packs of 1, 2, or 5 pieces to suit both single repairs and larger installations.

These BSP female fittings are well-suited for residential and commercial water supply lines, garden and agricultural irrigation systems, compressed air distribution networks, and light industrial fluid transfer applications where a corrosion-resistant, reusable threaded connection is required.

🔗 Compatibility Note: These fittings use BSP (G-thread, parallel) threads. They are not compatible with NPT (National Pipe Taper) threads. Verify your existing valves, pumps, or pipe ends are BSP-threaded before ordering.

⚠️ Sealing Tip: BSPP parallel female threads typically seal at the face using a bonded seal washer or O-ring — not PTFE tape alone. Confirm your connection type before assembly.

✅ Key Features of These SS304 BSP Female Thread Pipe Fittings

🔩Precision BSP Female Thread — Machined to BSP (G-thread) standards for consistent, repeatable engagement with standard male BSP fittings, valves, and pumps across plumbing and irrigation systems.
🛡️Stainless Steel 304 Construction — 18-8 grade stainless resists rust, oxidation, and mild chemical exposure, making these fittings a long-lasting choice for both indoor and outdoor pipe connections.
📐8 Sizes in One Listing — From 1/4" to 2", covering the most common BSP female thread sizes used in residential plumbing, compressed air lines, and agricultural irrigation fittings.
📦Flexible Pack Quantities — Order 1, 2, or 5 pieces per size. Buying a 5-pack reduces per-unit cost and keeps spares on hand for future repairs or multi-point installations.
🔄Reusable Threaded Design — Unlike push-fit or compression fittings, threaded BSP connections can be disassembled and reassembled, making them ideal for systems that require periodic maintenance or reconfiguration.
🚰Broad Fluid Compatibility — Suitable for water, air, and many mild industrial fluids. SS304 is widely used in food-processing, HVAC, and general-purpose fluid transfer pipe fitting applications.

❓ Frequently Asked Questions

How do I choose the right BSP female fitting size?

Measure the inside diameter (ID) of the pipe or the male thread you need to connect to. BSP sizes are nominal, not exact — for example, a 1/2" BSP fitting typically has an actual thread OD of about 20.9mm (≈0.825"). Match the fitting size to the male thread on your valve, pump, or pipe end. When in doubt, measure thread pitch and OD with a thread gauge before ordering.

What is the pressure rating of these stainless steel BSP fittings?

Stainless Steel 304 BSP fittings generally handle working pressures up to 150 PSI (≈10 bar) in standard plumbing and fluid transfer applications. Actual ratings depend on pipe wall thickness, temperature, and the fluid being conveyed. For high-pressure systems, please contact us to confirm suitability.

Are these fittings suitable for outdoor or marine use?

Yes. Stainless Steel 304 offers good corrosion resistance in most outdoor environments. For coastal or salt-spray environments, SS316 is generally recommended for longer service life. These 304 fittings are suitable for garden irrigation, outdoor plumbing, and light marine applications in most cases.

What thread standard do these fittings use — BSP or NPT?

These fittings use BSP (British Standard Pipe) threads, also known as G-thread (parallel). BSP and NPT threads are not interchangeable — they have different thread angles (55° vs 60°) and pitches. Always verify your existing fittings, valves, or pumps use BSP threads before ordering.

Do I need PTFE tape or a thread sealant with these fittings?

BSPP (parallel) female threads typically seal at the face using a bonded seal washer or O-ring — not PTFE tape alone. PTFE tape is generally used with tapered threads (BSPT). Check whether your male counterpart is parallel or tapered and use the appropriate sealing method to achieve a leak-free connection.

What fluids are compatible with SS304 pipe fittings?

Stainless Steel 304 is compatible with water, air, mild chemicals, food-grade liquids, and many industrial fluids. It is generally not recommended for highly chlorinated solutions or strong acids. For specific chemical compatibility, consult a compatibility chart or contact us before use.

Can I use these fittings for gas lines?

Stainless steel BSP fittings are used in gas applications in many industrial settings, but gas line installations typically require fittings certified to local codes (e.g., ANSI, CSA). Please verify local regulations and confirm the fitting's pressure and temperature rating before use in any gas system.

How many pieces come in each order, and which quantity is the best value?

You can choose from 1, 2, or 5 pieces per order using the Quantity(pcs) option above. Buying in packs of 5 offers the best per-unit value and ensures you have spares on hand for future repairs or multi-point installations.
