SEALMASTERS are able to supply seals to any size. Standard stock items cover both Imperial and Metric ranging from 3mm (1/8″) diameter (used in medical equipment) to 1 metre plus (40″+) as used in rolling mills and cement works. We also carry a stock of popular non-standard sizes.

Non-standard sized items can be made to order, again usually, with no additional tooling costs. This refers mainly to seals of built-up construction.

Standard Types Moulded and Bonded Lips

Manufactured to DIN 3760 / ISO 6194

Point contact single lip rotary shaft seal, with a rubber covered outside diameter and rear face. This style can accomodate split housings and housing bores where the surface roughness precludes metal to metal contact.

Type A

Point contact single lip rotary shaft seal, with a rubber covered outside diameter and rear face. This style can accomodate split housings and housing bores where the surface roughness precludes metal to metal contact.
A semi-dual rotary shaft seal, incorporating a minor lip for dust /dirt exclusion, or corrosion protection. With a rubber covered outside diameter and rear face, this style can accomodate split housings and housing bores where the surface roughness precludes metal to metal contact.

Type AS

A semi-dual rotary shaft seal, incorporating a minor lip for dust /dirt exclusion, or corrosion protection. With a rubber covered outside diameter and rear face, this style can accomodate split housings and housing bores where the surface roughness precludes metal to metal contact.

With a rubber covered outside diameter and rear face, this style can accomodate split housings and housing bores where the surface roughness precludes metal to metal contact. Suitable for pressures up to 10 bar.

Type ASHP

A high pressure semi-dual rotary shaft seal, incorporating a minor lip for dust /dirt exclusion, or corrosion protection. With a rubber covered outside diameter and rear face, this style can accomodate split housings and housing bores where the surface roughness precludes metal to metal contact. Suitable for pressures up to 10 bar.
A bonded rubber seal incorporating two spring loaded elements for separating two fluids and suitable for use where space is restricted. The rubber covered outside diameter can accomodate housing bores with a surface roughness.

Type AD

A bonded rubber seal incorporating two spring loaded elements for separating two fluids and suitable for use where space is restricted. The rubber covered outside diameter can accomodate housing bores with a surface roughness.
