1. Metallic gaskets
Enwere ụdị isi atọ:
(1) Octagonal na oval gaskets.Ha dị mma maka mkpuchi mkpuchi flange na trapezoidal grooves.
(2)Gasket nwere profaịlụ eze.The conical eze ripple na machined na akara n'elu metal flat gaskets, adabara nwoke na nwanyị flange ihu.
(3) Lens gaskets-adabara oghere flange akara na-ebupụta.A na-eme gaskets ọla site na igwe dị ọcha, igwe dị nro nwụrụ anwụ, igwe anaghị agba nchara, aluminom na ihe ndị ọzọ.
Elu chọrọ dị na machining nkenke na elu roughness nke sealing elu nke dara gaskets, na bolt nwere oké ịpị ike, otú ahụ gasket na-eji maka elu okpomọkụ na elu mgbali valves.

2. Metal-clad graphite gaskets
N'ozuzu, ha na-eji maka nwoke na nwanyị flange ihu na adabara valves na elu okpomọkụ na nrụgide.

3. Spiral ọnya gaskets
A na-etolite ha site na ịgwakọta na ịgbanye eriri igwe na-efegharị efegharị na teepu akara.Enwere eriri ígwè-asbestos, eriri ígwè-polytetrafluoroethylene, eriri ígwè-mgbanwe graphite, wdg N'ozuzu, a na-eji gaskets maka ihu flange nwoke na nwanyị ma dabara maka oke okpomọkụ na ọkara nrụgide valves.

4. Teflon gaskets
A na-ejikarị ha eme ihe maka mkpuchi ire-na-groove ma mee site na PTFE na PTFE nwere eriri iko.Ha dị mma maka mgbasa ozi corrosive siri ike na obere okpomọkụ na nrụgide dị iche iche.

5. Graphite gaskets
Flat gaskets mere site na graphite dị nro dabara adaba maka oke okpomọkụ na mgbasa ozi na-emebi emebi.

6. Paronite gaskets
Ha na-adabara na flange akara nke ire ụtọ, nwoke na nwanyị flange ihu na ire-na-groove flange ihu.Uru ndị a bụ ezigbo nguzogide corrosion na nkwụsi ike okpomọkụ, ezigbo plasticity, na obere ike ịpị iji hụ na akara.Mwepu bụ obere ike na mfe nrapado na flange akara elu.Paronite gaskets gụnyere bọọdụ asbestos, bọọdụ asbestos mgbochi corrosion.Ọtụtụ mgbe, a na-eme gaskets site na mbadamba asbestos, mbadamba asbestos na-eguzogide acid, mbadamba asbestos na-eguzogide mmanụ, mbadamba asbestos nwere waya ígwè na ihe ndị ọzọ.A na-eji ha maka valvụ nrụgide ọkara na oke okpomọkụ.
