very boring Strainer Hose Connector question...

[ChasB]

I've just bought two strainers for my big Volvo engines from ASAP. They were described as having 1-1/2" BSP female ports, which I took to mean they would connect to 1.5" hose.

However the threaded holes are nearly 2" in diameter. But maybe this is OK...?

I couldn't find any suitable connectors on the ASAP site (a strange omission) but found these brass ones at Mailspeedmarine

1.5" straight - £14.99

£15 each! That means shelling out another £60. Damn.

1) Are these the correct item to purchase?

2) Can I get them cheaper elsewhere? Maybe use plastic ones? Who from?

3) any other tips?

1 1/2" BSP, means the inside diamater of the pipe that will fit those fittings. ASAP have those fittings, because I have just bought some, maybe your not looking in the right place? But £15 quid is about right, they are fairly large.
BUT I would not be fitting brass fittings in my salt water engine intake system, you need bronze/gunmetal, have another look at the ASAP site. Maybe plastic (Glass re-inforced nylon or summat) fittings are available, dunno. Maybe from vetus?

BSP thread size refers to the nominal bore of the pipe, and the actual diameter is controlled by the outside diameter of the pipe, and hence is rather larger. Do you want "hose tails"? ASAP do 1.5in.BSP x 38mm for around £5 in brass, £12 in gun metal.

Cheers guys. I now seem t have found the appropriate item

HOSETAIL 1.5 in.BSPMALE TO 38mm HOSE GM

Still £60 with VAT though /forums/images/graemlins/frown.gif

For future reference 'Female ports' means the fitting goes inside it.

Thanks.

Just occurred to me -

Do I need to use a sealant on the joints? or some kind of rubber washer?

BTW since the strainer is ahead of the engine, water will be sucked in, so any leaks will suck air in rather than push water out.

Cheers.

PTFE, in the form of either liquid sealant or tape.
