JOINER REDUCING SOCKET BSP 1 1/2" (40mm) X 1" (25mm) PHILMAC 90435300 at a glance

Philmac’s robust threaded fittings provide precision BSP tapered threads that have been engineered to maximise sealing performance.

The versatile range is made from high performance, UV resistant polypropylene that does not absorb moisture.

Installation is quick, simple and reliable every time.

The material is also potable water (AS/NZ 4020) approved. (Note: Products marked “Ancillary” are not potable water approved.)

Philmac’s threaded fittings provide maximum versatility, delivering a high performance connection across a wide range of pressure ratings and chemical combinations.

The hexagonal body makes them extremely simple to install. Importantly, Philmac threaded fittings are suitable for working pressures up to PN16 for sizes up to 2”, PN12 for 2-1/2” and PN10 for 3” and 4” sized fittings.

Smart hexagonal design makes the fittings compatible with tools and ensures that Philmac BSP threaded fittings are extremely easy to install.

Philmac threaded fittings are manufactured from high quality materials that ensure strong connections for many years.

The material also has a high degree of UV resistance to ensure long term performance even in direct sunlight.

This reducing socket connects 1 1/2" (40mm) BSP threaded male connections to 1" (25mm) poly pipe. Wrap the male threads with PTFE tape (3-4 layers) before screwing into the socket to ensure a watertight seal. Hand-tighten first, then use an adjustable wrench to firmly secure without over-tightening, which can crack the fitting. Ensure the poly pipe is clean and insert it fully into the barbed end if connecting via barb, or use appropriate clamps if needed. Tips: Always use stainless steel clamps on barb connections to prevent corrosion in Queensland's climate. This fitting is ideal for reducing pressure from pump discharge lines or connecting smaller diameter poly pipe to larger threaded sources. Check your system pressure rating (rural poly pipe is rated to 800kPa) to ensure this fitting is suitable for your application.

Common Questions

What is this fitting used for?

This is a joiner reducing socket that connects two different sized BSP threaded pipes — a 1 1/2" (40mm) thread on one end and a 1" (25mm) thread on the other. It's used to join pipes of different diameters in your irrigation or water system.

Is it safe for drinking water?

Yes, this fitting is potable water approved to AS/NZ 4020, so it's safe to use in systems supplying drinking water.

What pressure can it handle?

This fitting is suitable for working pressures up to PN16 for sizes up to 2".

How do I install it?

The hexagonal body design makes installation simple and reliable. You'll need a wrench or spanner to fit the hex — the tapered BSP threads seal themselves as you tighten. No special tools or expertise required.

Will it last in the sun?

Yes. It's made from UV resistant polypropylene and is designed to perform long-term even in direct sunlight, so it won't degrade outdoors.
