No licence claim for radio links

TECSTAR Electronics has introduced a pair of two-way radios which it claims can be used without a licence and over a two-mile distance.

Offering eight channels, the RS446 radios have a call alert button, an automatic battery save function plus a backlit LCD display which indicates volume/battery level and channel number. They can also operate with a range of sub-channels to prevent interference from other radio users.

Available with an optional socket for external headphones, the RS446 two-way radios costs £89/pair (01480-399503).

Socket set will grip most awkward nuts

SPALDINGS has now introduced a 1/4in drive socket set to complement its existing 3/4, 1/2 and 3/8in drive sets.

The latest Truecraft set is equipped with 39 pieces ranging from metric 4mm to 12mm and 3/16 to 1/2in sockets.

For reaching awkwardly positioned nuts, the set also contains a selection of deep sockets in sizes ranging from 4mm to 12mm and 3/16 to 1/2in.

Supplied with a ratchet and two extension bars, the Truecraft 1/4in drive socket set is priced at £19.99 (01522-500600).

Lip seal designed for pressure work

BSL has developed a lip seal for use in high pressure equipment, such as industrial pumps and compressors.

The PS61 seal features a durable Gylon lip and an internal Viton gasket to prevent fluid and gases from escaping at high pressure.

Designed to fit shaft diameters from 8mm to 140mm, the PS61 lip seal is claimed to be more effective at reducing slow leakage when compared with mechanical seals.

The lip seal is clamped into a stainless steel case which, along with the Viton gasket, is suitable to withstand pressures up to 10bar, according to BSL (0161-953-8633).
